Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Portland, Maine Bicycle Approaches to Tukey’s Bridge Executive Summary Gorrill-Palmer Consulting Engineers, Inc. has been retained by PACTS to complete a review of the bicycle accommodations approaching Tukey’s Bridge from the Portland Peninsula as well as the East Deering Neighborhood of Portland, and to identify potential entrance treatments on the Peninsula side of Washington Avenue. The City currently has or is planning bicycle facilities both on and off street in the vicinity of Tukey’s Bridge, but actual connections to the Tukey’s crossing are inadequate or circuitous. This report is intended to identify the deficiencies and provide options to improve the access. The plan provides focus for the capital investments necessary to provide a short term approach to safer pedestrian/bicycle circulation, and identifies potential longer term measures. Our office completed an inventory and evaluation of the existing facilities on each side of Tukey’s Bridge and proposes the following improvements to the facilities as shown on Figures 1 through 4 of Appendix A. Peninsula Approach ¾ Widen the sidewalk along the west side of Washington Avenue from Eastern Prom to Tukey Street (Anderson Street ramp) to provide a multi-use path. ¾ Construct a separated multi-use path along the northwest side of Tukey Street to connect with the Bayside Trail. Washington Avenue Entrance Treatment from the Peninsula ¾ Provide median with entrance treatment features such as landscaping and signing on the Washington Avenue approaches to Eastern Prom. ¾ Long-term consideration of a potential roundabout at the Eastern Prom intersection. East Deering Approach ¾ Provide direct access from the end of Bates Street to the Back Cove trail. ¾ Relocate a portion of the sidewalk along the Washington Avenue on-ramp to southbound I295 to address sight distance issues created by the retaining wall along the west side of the ramp. ¾ Long term consideration should be given to widening this ramp to provide suitable bicycle access from the Back Cove along this ramp to the Bates/Veranda intersection to avoid at-grade crossing of Baxter Boulevard/I-295 ramp terminals. P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 1 Portland, Maine Bicycle Approaches to Tukey’s Bridge Chapter 1 Introduction Tukey’s Bridge crosses the mouth of Back Cove and is the confluence of I-295 and Washington Avenue as well as the Back Cove and Eastern Prom multi-use trails. There is a complicated highway ramp system in this area that makes bicycle connections very difficult and/or circuitous. This study encompasses the approach areas on each side of Tukey’s Bridge as well as a connection to the proposed Bayside multi-use trail. The Peninsula approach to Tukey’s is along Washington Avenue, with no legal bicycle connection to the bridge. Bicyclists have been observed crossing Tukey’s Bridge on the Interstate shoulder (the bicycle prohibition sign is located almost on the bridge), as well as the Tukey’s shared use sidewalk by proceeding in the shoulder against inbound ramp traffic or using the sidewalk along Washington Avenue to reach the bridge shared use sidewalk. These methods of approaching Tukey’s Bridge are not desirable or safe means of access. The Back Cove Trail does have a loop connection under Tukey’s Bridge to Marginal Way and the Eastern Prom Trail. However, this is a circuitous route for reaching downtown destinations. The Back Cove Trail provides access to the Tukey’s Bridge crossing from East Deering, but getting to the trail from the Washington Avenue/Bates Street/Veranda Street intersection is inconvenient and involves a difficult crossing of Baxter Boulevard. There is a bike lane along Bates Street, but to reach the trail, bicyclists are currently directed to use a pedestrian crosswalk on Baxter Boulevard. As an alternative, some bicyclists are using the five-foot wide sidewalk along the Washington Avenue southbound on-ramp to I-295. This is hazardous to pedestrians, particularly in one section where a tall, curved retaining wall blocks sight distance. Speeds along the Peninsula side of Washington Avenue are of concern due to the fact that the I295 ramp terminals are an extension of Washington Avenue. This is not so problematic on the East Deering side since there is an immediate signalized intersection with difficult geometrics. Therefore, in the interest of improving pedestrian and bicycle crossing safety, this report also addresses potential entrance treatments on the Washington Avenue side of Tukey’s Bridge. This report is intended to investigate options for improving bicycle access on the approaches to Tukey’s Bridge. The goal of the plan is to identify alternatives that can be implemented quickly and at reasonable costs as well as longer term measures that may optimize the safety and convenience of access. P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 2 Portland, Maine Bicycle Approaches to Tukey’s Bridge Chapter 2 Existing Conditions Peninsula Approach There are two ways to access the Peninsula end of Tukey’s Bridge. One is via Washington Avenue and the other is via Tukey Street, i.e. the one-way ramp from the Bridge to Anderson Street. Each of these approaches is described below. Washington Avenue Washington Avenue is a major arterial for access to downtown Portland. North of Eastern Prom, Washington Avenue has a twelve foot travel lane and eight foot shoulder in each direction. The roadway widens to three lanes (two inbound and one outbound) with six foot shoulders and divides at the ramp terminals to I-295. There is a six foot sidewalk along the west side of Washington Avenue that is separated from the roadway by a guardrail. There is an overhead pedestrian crossing sign array at the Eastern Prom intersection. There is no posted speed on Washington Avenue inbound until Eastern Prom where a 25 MPH limit is posted. There is a 30 MPH ramp advisory speed sign at the exit from I-295. There is no posted speed on outbound Washington Avenue, with the assumption that the 25 MPH speed on the downtown side of Washington Avenue applies north of Eastern Prom. However, that speed limit is not adhered to by drivers; nor is the 30 MPH ramp advisory speed. There is no legal crossing of Tukey’s Bridge on outbound Washington Avenue. A mounted bicyclist should not use the existing sidewalk as shown below to reach the Tukey’s Bridge shared Figure 2.1: Washington Avenue Existing Conditions Figure 2.2: Washington Avenue Existing Typical Section P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 3 Portland, Maine Bicycle Approaches to Tukey’s Bridge use sidewalk, and bicyclists are not allowed on the outbound shoulder of the bridge. Therefore the existing conditions shown in the previous Figures are only for inbound Washington Avenue. Tukey Street Tukey Street is a one-way ramp from the Washington Avenue off-ramp to Anderson Street, but is not heavily used. There is no posted speed, with the Washington Avenue off-ramp advisory speed of 30 MPH assumed to apply. Tukey Street is 28 feet wide with no pavement markings. There are no pedestrian or bicycle accomodations along Tukey Street. Tukey Street is stop controlled for left turns onto Anderson Street and yield-controlled for right turns onto Plowman Street at the bottom of the ramp. Figure 2.3: Tukey Street Looking from Anderson to Washington Figure 2.4: Tukey Street Existing Typical Section Washington Avenue Ramp at Tukey Street The Washington Avenue sidewalk is connected to the Washington Avenue Ramp shared-use sidewalk by a crosswalk across Tukey Street. The ramp sidewalk is approximately 7’ 6” wide with a 54” metal railing on the outside and a 32” concrete barrier on the vehicular traffic side. The concrete barrier and railing transition to guard rail at the end of the bridge. The street-side guard rail ends at the crosswalk while the guardrail at the back of the sidewalk continues on Tukey Street. The interface between pedestrians/bicyclists and vehicular traffic is very complicated at this location. The crossing is around the curve leading from the Washington Avenue ramp onto Tukey Street causing sight distance concerns for motorists and pedestrians/bicyclists. The intent of approaching drivers is often unclear as to whether they are turning onto Tukey Street as many do not signal for this movement and speeds are high. These concerns and existing conditions are depicted in the following photographs: P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 4 Portland, Maine Bicycle Approaches to Tukey’s Bridge Figure 2.5: Pedestrian Crossing partially obscured Figure 2.6: Pedestrian and Bicyclist assessing Crossing East Deering Approach Bicyclists approaching from the north on Baxter Boulevard can easily get onto the Back Cove Trail to reach Tukey’s Bridge. However, those coming from Veranda Street or Presumpscot Street must negotiate the Washington/Veranda/Bates intersection, utilize Bates Street, and cross the Baxter Boulevard/I-295 ramp terminals or walk/illegally ride the five foot sidewalk along the Washington Avenue southbound ramp to I-295. Bates Street Route This route is assigned as the East Coast Greenway. Bates Street serves as the access to Baxter Boulevard as well as the I-295 northbound on ramp and southbound off ramp. There is one travel lane in each direction with bike lanes mid-block. Approaching Washington Avenue, Bates street quickly widens to what is essentially 2 ½ lanes plus an intermingled bike lane. Approaching Baxter Boulevard, Bates Street splits to provide a right turn yield-controlled roadway to enter onto Baxter Boulevard. Bates Street straight-ahead is stop-controlled for the left turn onto Baxter Boulevard to the I-295 northbound ramp terminal. Bicyclists need to follow the right turn roadway, dismount and cross in a pedestrian crosswalk over the right turn roadway and the I295/Baxter Boulevard ramp terminals for I-295 north of Portland to enter the Back Cove Trail. Bicyclists headed outbound to East Deering and Falmouth need to make a u-turn at this crosswalk, proceed east on Baxter Boulevard and then make a left turn onto Bates Street. These conditions are depicted in the following photographs: P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 5 Portland, Maine Bicycle Approaches to Tukey’s Bridge Figure 2.7: Pedestrian crossing of Baxter Boulevard to Back Cove Trail Figure 2.8: Left onto Bates from Baxter Boulevard Figure 2.9: Approach to Washington Avenue from Baxter Boulevard Washington Avenue/Ramp Sidewalk Route This is currently not a legal route for a mounted bicyclist as it consists of a five foot wide sidewalk. Exacerbating the use of the five foot sidewalk as a riding route is the presence of a tall, curved retaining wall that obscures sight distances. Although there are some portions of this route that are relatively unconstrained and could be easily widened, the noted retaining wall as well as bridge abutment treatments would make upgrading this route very difficult. The following photos depict the constrained conditions in the vicinity of the wall and abutments as well as more open conditions where the sidewalk is separated from the roadway and where there is no retaining wall: Figure 2.10: Sidewalk at Wall Figure 2.11: Sidewalk in unconstrained Area Figure 2.12: Sidewalk at Abutment P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 6 Portland, Maine Bicycle Approaches to Tukey’s Bridge Chapter 3 Identification of Alternatives Peninsula Approach Two options to provide bicycle access for each of Washington Avenue and Tukey Street have been identified. These are shown on Figures 2 & 3 of the Appendix and are described below: Washington Avenue Access from Washington Avenue can be provided only along the west side of Washington Avenue since this is the location of the existing shared use sidewalk on the Washington Avenue ramp from I-295/Tukey’s Bridge. Therefore a shared use path separated from the roadway is required. This separation can be either by distance or by a barrier. Since Washington Avenue in this area is on a steep, high embankment, it is most practical to use a barrier for separation. Ideally, a twelve foot path would be provided, with a minimum of ten feet acceptable. We have evaluated using a twelve foot width from the face of curb to edge of the path, yielding a net width of 10’ to 10’ 6” when deducting for barriers. Two options for providing this path have been identified as follows: Option A: Reduced Roadway Shoulder To minimize impacts due to the steep embankment, this option would narrow the ten-foot shoulder on Washington Avenue to six feet and then widen the existing sidewalk by two feet to provide a total width of twelve feet minus barriers as shown in the following typical section: Figure 3.1: Peninsula Approach Option ‘A’ It may be desirable to use a combination railing/guardrail along the street side for durability, particularly for snow plowing operations. Also, since the shoulder is somewhat narrower in the four-lane section of Washington Avenue, this option would include a portion in accordance with Option B in the vicinity of Tukey Street. Also common to both options is placement of an Interstate pedestrian/bike prohibition sign on Washington Avenue immediately north of Eastern Prom so that bicyclists are notified at a point where they can reroute without riding against ramp traffic. P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 7 Portland, Maine Bicycle Approaches to Tukey’s Bridge Option B: Maintain Existing Shoulder Should maintenance of the existing shoulder width on Washington Avenue be a desirable objective, the full extent of the widening to achieve a twelve-foot wide shared use path could be achieved through use of a retaining wall. The existing Washington Avenue curb line would be preserved and a wall varying in height from two to four feet would be needed along the widened edge of the path. This would require a railing along both sides of the path for separation from traffic on one side and to limit exposure to the wall drop-off and steep slope on the other side. This option is depicted in the following typical section: Figure 3.2: Peninsula Approach Option ‘B’ Tukey Street This one-way street that serves as a ramp from Tukey’s Bridge to Anderson/Plowman Streets will be an important link to the planned Bayside Trail. Given the ramp width, it is possible to provide bike lanes on each side within the existing paved area, or a curb line could be moved to provide a separated path. Similar to the Washington Avenue approach, steep grades on each side of Tukey’s Street present challenges to the work. One consideration in the selection of an option is the location of the Bayside trail to the north side of Tukey Street. Placing a separated path on the north side of Tukey Street would limit the number of street crossings required to reach the shared use sidewalk on Tukey’s Bridge. This is of particular importance at the top of the Street/ramp where vehicular speeds and driver intent greatly complicate the crossing maneuver. Both options would have one element in common: improve safety at the top of the ramp. We propose to accomplish this through modification of the curb line for traffic bearing right from the Washington Avenue/Tukey’s Bridge ramp onto Tukey Street. The following excerpt from the plans in Appendix A depicts the change to the curb line: P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 8 Portland, Maine Bicycle Approaches to Tukey’s Bridge Figure 3.3: Curb Adjustment at Washington Avenue/Tukey’s Bridge Ramp at Tukey Street This adjustment would accomplish several goals: first would be to tighten the radius slightly to slow exiting traffic; second would be to shift the observation point for crossing pedestrians and bicyclists to provide a better view of approaching vehicles; third would be to make the pedestrian/bicyclists more apparent to drivers; and fourth would be to “shadow” the bike lane or path on Tukey Street. Option A: One-Way Bicycle Lanes & Sidewalk This option would provide six foot bike lanes on each side of Tukey Street, and leave a sixteenfoot vehicular travel lane between them. This option would also include a five-foot sidewalk on the south side of the street to provide pedestrian access to the bridge. Although this is a viable option, we do have concerns for safety relative to a contra-flow bike lane on what is essentially an off-ramp, and the somewhat complicated interface at the intersection with Washington Avenue. A variation of this option would be to provide an eight-foot wide multi-use sidewalk on the south side in lieu of the contra-flow bike lane. This option is depicted in the following typical section: P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 9 Portland, Maine Bicycle Approaches to Tukey’s Bridge Figure 3.4: One-Way Bicycle Lanes with Sidewalk (Option ‘A’) Option B: Shared-Use Path This path would be along the north side of Tukey Street and would be accomplished by shifting the north curb line to narrow Tukey Street to nineteen feet. This would allow a twelve-foot shared use path separated from the street with a pedestrian/bike railing. Unlike Washington Avenue, this route would not need a guard rail as snow would likely all be plowed to the south, reducing durability concerns. Also, vehicular momentum to the south on this ramp reduces any likelihood of crossing a curb on the north side of the ramp. As noted earlier, this option minimizes crossings of Tukey Street by placing all pedestrians and bicyclists on the same side of the street with the Bayside Trail and Tukey’s Bridge. This option is depicted in the following typical section: Figure 3.5: Shared-Use Path (Option ‘B’) Tukey Street at Anderson Street/Plowman Street The current configuration has a delta island with a right turn slip lane that is in close proximity to the Bayside Trail. Figures 2 & 3 show the minimum treatment of converting the slip lane to “stop” control due to its proximity to the Bayside Trail. Figure 3 also shows an alternative treatment to eliminate the slip lane and delta island that would require relocation of a large utility pole. P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 10 Portland, Maine Bicycle Approaches to Tukey’s Bridge East Deering Approach Two options to provide bicycle access from East Deering to Tukey’s Bridge have been identified. These are shown on Figure 5 of the Appendix and are described below: Option A: Bates Street Extension This option addresses the current need for bicyclists to dismount to legally cross Baxter Boulevard/I-295 ramp terminals to arrive at the Back Cove Trail or to leave the Back Cove Trail bound for Bates Street. This option provides for a fourth, bicycles- only, leg to the Bates Street intersection that connects directly to the Back Cove Trail. Two one-way connections are proposed to provide proper alignment with Bates Street without an unduly wide connection to the Trail. To enter the Trail, bicyclists proceeding southwest along Bates Street would cross the right turn roadway leading to Baxter Boulevard westbound and proceed straight along Bates Street to the stop controlled intersection with Baxter Boulevard. A connection to the Back Cove Trail, which bicyclists could reach by proceeding straight across this intersection, would be provided. Similarly, a connection aligning with the existing Bates Street northeast-bound bike lane would be provided for cyclists leaving the Trail. We anticipate that this crossing may be limited to more advanced bicyclists due to the difficulty of the intersection, and recommend maintaining the option of utilizing the existing crosswalk for less experienced cyclists. The following plan excerpt shows the proposed connection: Figure 3.6: Bates Street Connection (Option ‘A’) P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 11 Portland, Maine Bicycle Approaches to Tukey’s Bridge Option B: Ramp Sidewalk Widening Providing a suitable shared use sidewalk along the Washington Avenue/I-295 SB on-ramp may be the better option for connecting to Tukey’s Bridge as it allows for grade-separated crossing of the I295 ramps/Baxter Boulevard. The outbound crossing to Veranda Street at the Bates/Washington/Veranda intersection may be somewhat complicated, but this may be preferable to the at-grade crossing of Baxter Boulevard. However it is far more challenging relative to construction and costs. The first challenge would be to relocate the significant retaining wall shown in the existing conditions photos. This would likely have impacts on the commercial property (parking lot) that sits atop this retaining wall. The second challenge would be the modification of the abutment treatments for the I-295 ramp overpasses. We recommend this option for further study as the preferred approach to East Deering. The following plan excerpt depicts the existing sidewalk route: Figure 3.7: East Deering Ramp Sidewalk (Option ‘B’) Washington Avenue Entrance Treatments As previously mentioned, the speed of traffic entering and leaving the I-295 ramp terminals are of concern for pedestrian and bicycle crossings in the vicinity of Eastern Prom. There is a marked crosswalk with an overhead pedestrian crossing sign assembly, but vehicular speeds appear to be in the 35 MPH+ range through the intersection and Washington Avenue is about 40 feet wide in this area. We have evaluated various measures to address the speeds as follows: Speed Limit Signage The 30 MPH ramp advisory speed for southbound I-295 traffic exiting to Washington Avenue is not heeded by motorists in general, and the first regulatory speed sign (25 MPH) is immediately in advance of the Eastern Prom intersection. We recommend a regulatory 30 MPH speed limit sign be posted on the ramp in advance of the Tukey Street exit to make this the legal speed limit. This may help to reduce vehicular speed prior to the 25 MPH limit at the Eastern Prom intersection. P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 12 Portland, Maine Bicycle Approaches to Tukey’s Bridge There is an outbound 25 MPH speed limit sign on Washington Avenue approximately 500 feet south of Eastern Prom, but this appears to be quickly forgotten by outbound drivers. There is a regulatory 35 MPH speed limit sign about 800 feet north of the Eastern Prom intersection. We recommend placement of a 25 MPH speed limit sign immediately north of the Eastern Prom intersection to reinforce the lower speed through the intersection. Option A: Roundabout Treatment This option is depicted on Sheet 4 of the Appendix. While this would provide a very definitive entrance treatment that would slow traffic through the Eastern Prom intersection, the grades in this area would be very challenging. The steep grades down to the west and up to the east would likely result in retaining walls up to twenty feet tall in spots. Further study and evaluation of grades is needed to fully assess this option, which could include an oblong as opposed to circular roundabout. The following plan excerpt shows the roundabout option: Figure 3.8: Potential Roundabout Treatment (Option ‘A’) P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 13 Portland, Maine Bicycle Approaches to Tukey’s Bridge Option B: Median Treatment The width of Washington Avenue at the Eastern Prom intersection would allow placement of an eight or ten foot wide raised median on both approaches. There is room for a 50 foot long median on the south side of the intersection without blocking driveways, and we recommend a 75 foot long median on the north side where there are no driveways. The median would provide an entrance treatment that would narrow the pavement and help control speeds, and also provide a pedestrian refuge. Figure 3.9: Potential Median Treatment (Option ‘B’) P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 14 Portland, Maine Bicycle Approaches to Tukey’s Bridge Chapter 4 Preliminary Opinions of Probable Construction Cost Gorrill-Palmer Consulting Engineers, Inc. has prepared preliminary opinions of probable construction costs for the various treatments that have been identified, except for those requiring further study. These are the roundabout option and the Washington Avenue SB I-295 ramp sidewalk option. The following preliminary opinions of probable construction costs do not include the following: ¾ Legal or Engineering Costs ¾ Remediation or removal of hazardous materials ¾ Right-of-way costs ¾ Wetland remediation or permitting ¾ Utility relocations Costs based on MaineDOT 2008 unit prices as follows: Preliminary Opinion of Probable Construction Costs Improvement Opinion of Cost Washington Avenue Option A – Reduced Shoulder Option B – Maintain Shoulder Tukey Street (Anderson Street Ramp) Option A – Bike Lanes Option B – Shared Use Path East Deering Bates Street Extension Washington Avenue Entrance Treatment Median $168,000 $286,000 $ 42,000 $162,000 $ 45,000 $ 46,000 P.O. Box 1237/15 Shaker Road Gray, Maine 04039 207.657.6910/[email protected] JN 2228 Page 15 Portland, Maine Bicycle Approaches to Tukey’s Bridge Chapter 5 Recommendations Gorrill-Palmer Consulting Engineers, Inc. recommends the following for short-term actions to improve access to Tukey’s Bridge: Peninsula Approach Option A – Reduced shoulder to provide path widening is recommended for Washington Avenue to minimize impacts to the steep embankment on the east side of Washington Avenue and to provide roadway narrowing to help with speeding concerns. Option B – Shared Use Path is recommended for Tukey Street as this provides the safest most convenient option and would be the long-term solution for this approach. Institute “stop” control for slip lane on Tukey Street at Plowman Street. Installation of medians for entrance treatment and to provide pedestrian refuge is recommended for the Eastern Prom intersection regardless of the selected bicycle path option. East Deering Approach Construction of the Bates Street extension (bicycles only) is recommended as a short-term measure to improve access to/from East Deering. However, further study should be provided to assess the possibility of widening the Washington Avenue/I-295 SB sidewalk to be a shared use sidewalk. P.O.
