construction and 30 year maintenance of the following:
Freeway
Anthony Henday Drive (Manning Drive to Yellowhead Trail):
@9 km of new six-lane and eight-lane divided freeway through undeveloped land.
Anthony Henday Drive (Yellowhead Trail to Whitemud Drive):
@9 km of reconstructed six-lane and eight-lane divided freeway.
Yellowhead Trail (North Saskatchewan River to Sherwood Drive):
@6 km of reconstructed six-lane and eight-lane divided freeway.
Sherwood Park Freeway (Anthony Henday Drive to 17 Street):
@3 km of reconstructed six-lane divided freeway
Utilities
@Over 500 utility crossings.
@Approximately 300 locations which require protection or relocation of
existing utilities.

Structures
Total of 46 bridges, comprised of 37 highway bridges, 7 rail bridges and 2 river bridges.
-Manning Drive
-Yellowhead Trail
-Sherwood Park Freeway
Service interchanges:
-153 Avenue
-130 Avenue
-Baseline Road
-Broadmoor Boulevard/Yellowhead Trail
-17th Street/Sherwood Park Freeway
-Sherwood Drive/Yellowhead Trail
Flyovers:
-Victoria Trail
-Petroleum Way
-Seven railways including Clover Bar Yard
@There will be twin river bridges over the North Saskatchewan River with a pedestrian
and cycle bridge below one of the bridges.
@The project requires 103 overhead signs.
Background
@The preliminary design, which included environmental and noise assessment as well as a
public consultation program, was previously completed.
@The public consultation included three sets of open houses held in November 2008,
June 2009 and February 2011.
@Information regarding the functional plan, access plan, noise study, environmental and
the history and background of the corridor development was displayed. The public was
encouraged to provide their feedback on the preliminary design to the team for consideration

Frequently Asked Questions:
Q !
!"#$
A Land within the TUC is primarily set aside for roads, utilities and pipelines. We will accommodate pedestrians
and cyclists along most of the crossroads; however, the construction of multi-use trails is not part of Alberta
Transportation’s mandate.
After construction is completed in 2016, areas of the TUC may be available to lease for surface use. See Alberta
Infrastructure’s website, www.infrastructure.alberta.ca for information on leasing land within the TUC.

A The contractor will provide a minimum of two lanes in each direction for all main roads including Anthony Henday
Drive, Yellowhead Drive, Sherwood Park Freeway, Baseline Road, Broadmoor Boulevard, Sherwood Drive, and
Whitemud Drive and a minimum of one lane in each direction for minor roadways. All directional movements at
interchanges will also be maintained. The contractor will provide access to individual properties at all times.

Plant Relocation Project:
One rare plant species, marsh muhly, is present at the North Saskatchewan River crossing. In autumn 2012,
under the supervision of a rare plant specialist, these plants will be relocated to new sites with similar habitat,
within the TUC, that will not be disturbed in the future.
Wildlife - Best Management Practices:
CAPITAL CITY LINK GROUP has incorporated best management practices to minimize disturbance to wildlife
during construction:
@Vegetation will be cleared so as to avoid disturbance of active breeding habitat.
@Erosion controls will minimize potential sediment release into local ponds, ditches and creeks.
Wetland Compensation Plan
Under the Alberta Water Act and the associated Interim Wetland Management in the Settled Area
of Alberta - An Interim Policy (1993) Provincial Wetland Restoration/Compensation Guide (2007),
wetland loss must be compensated at a minimum ratio of 3:1 (wetland area replaced to wetland
area lost).
To construct the project, approximately 20 hectares of wetlands will need to be disturbed or
removed, and approximately 60 hectares of wetland will be created as compensation. The
majority of compensation will be generated within the TUC as constructed wetlands. Any
remaining and necessary compensation will be achieved through participation in Ducks Unlimited
Canada’s Cooking Lake wetland restoration initiative.
The compensatory wetlands will provide several important
functions including provision of wildlife habitat.
North Saskatchewan River Crossing
CAPITAL CITY LINK GROUP is committed to protecting the North Saskatchewan River and river valley, and
the species that depend upon them. Protective measures include:

Noise Attenuation Guidelines for Provincial Highways under Provincial Jurisdiction
within Cities and Urban Areas
)(
Noise - the sound generated by vehicles operating on provincial highways.
*#
A noise level of 65 dBA Leq24*, measured 1.2 m above ground level and 2 m inside the property line
(outside the highway right-of-way), adjusted to 10-year planning horizon value is the threshold to consider
noise mitigation measures.
Noise mitigation alternatives are noise walls and/or berms. Implementation will consider cost, technical
practicality, resident support, and provincial priorities.
Accepted noise mitigation measures will be the responsibility of Alberta Transportation in areas where
Alberta Transportation is undertaking widening or major realignment of an existing road or constructing a
new road adjacent to an existing residential development.
For new residential subdivisions constructed adjacent to an existing roadway, the developer will be
responsible for noise attenuation.
For new residential subdivisions constructed adjacent to a designated highway that has not been
constructed, Alberta Transportation will request that the development proponent and approving authority
address future noise concerns.
*Noise levels expressed in decibels (dB) is taken to mean the A-weighted 24-hour equivalent sound level.
