Resurfacing and
Safety Improvements
Project No. 608022
Public Information Meeting
February 9, 2016
Project Location
The project begins at the intersection of New Holland Road
and extends east into Sturbridge to just west of Galileo Drive,
approximately 4.06 miles.
Existing Typical Section – Route 20
Four Lanes Each 11’ Wide – No Shoulders
Funding & Schedule
Funding
80% Federal and 20% State Funds
$3.6 million Total Cost
Schedule
Advertising date - Early 2016
Construction expected to begin Fall 2016 or Spring 2017
Purpose of Project
Implement
safety improvements to
address crashes
Resurface
the pavement
Design Process to Date:
Safety
Analyzed crash records
Conducted a Road Safety Audit
Analyzed proven safety measures for applicability to Route 20
Speeds
Recorded traffic speeds
Traffic Volumes
Obtained traffic volume counts from permanent counting station
Studied special event traffic - Brimfield Flea Market
Additional
Multiple site visits to evaluate project area
Met with Brimfield Select Board
Developed detailed design plans for the project
Town Request for Safety Improvements
August 2014 Select board letter to MassDOT requesting
safety features
Concerns:
High speeds
Fatalities
No breakdown lanes
Crash Rate Findings
There have been 4 crashes involving fatalities
from 2006 - 2015 (5 total fatalities)
The fatal crash rate for Route 20 is 4 times higher
than the statewide average for rural roads
4.70 fatalities per hundred million vehicles miles
traveled
Crash Rate Findings (Continued)
Data Summary
There were 17 crashes
from 2011 – 2013
Majority single vehicle
0.48 crashes per
million vehicle miles
traveled
0.90 crashes per
million vehicle miles
traveled, statewide
average for rural roads
Road Safety Audit
What is the RSA?
Formal safety examination of
roadway by multidisciplinary team
Purpose
To identify safety issues and
possible improvements
considering all roadway users

Analysis of Safety Measures
Proposed Actions
Issue: Lack of shoulders
Proposed action: Provide usable shoulders & shoulder
rumble strips
Issue: No Separation between EB/WB lanes
Proposed action: Provide centerline rumble strips
Issue Sight distance issues
Proposed action: Cut back trees, brush, provide
shoulders, & provide advanced warning signs for
intersections
Issue: No Left Turn accommodations
Proposed action: Provide Left Turn storage at key
intersections and commercial driveways
Proposed Actions
Issue: High speeds
Proposed action: Convert 4-Lanes to 2-Lane cross
section, install reduced speed limit ahead sign, install
dynamic speed feedback sign (entering Brimfield)
Issue: No pedestrian or bicycle accommodations
Proposed action: Provide paved shoulders/bike lane &
bike friendly shoulder rumble strips
Issue: Lack of lighting/delineation
Proposed Action: Provide reflectorized delineators,
durable wet reflective pavement markings & slotted
pavement markers
Proposed Actions
Issue: Inclement weather build up
Proposed Action: Remove drainage structure sediment,
clear debris from shoulders & ditches, replace deficient
structures
Issue: Sunken Drainage Structures
Proposed Action: Adjust drainage structures, install
bike friendly grates & install shoulders so grates are no
longer in travel lane.
The primary safety improvement on the
project is to reduce Route 20 to 1 lane
in each direction

Example Left Turn Lane
Benefits of Shoulders
Reduces numerous crash types
Head (15%-75% reduction)
Sideswipe (15%-41%)
Fixed Object (29%-49%)
Pedestrian walking along roadway (71%)
Provides emergency stopping space for
broken down vehicles
Improves drainage & reduces shoulder
maintenance
Provides space for maintenance operations
and snow storage
Increases effective turning radii at ints.
Provides space for variable message signs
Provides an increased comfort for cyclists
Provides stable surface off roadway for
peds

Allow shoulder use
during event
Use temporary variable
message signs or
permanent roadside
“flip” signs to alert
drivers
