SWAHD – Project Information
SOUTH WEST ANTHONY HENDAY DRIVE
- The South West Anthony Henday Drive (SW AHD) was opened in 2006. It provides a transportation route around south west Edmonton with connections to, and from, the city at key locations. It is part of 80 km ring road around Edmonton.
- During the design and construction of this portion of the AHD, preliminary grading occurred for two additional lanes in each direction of traffic from Calgary Trail to north of Whitemud Drive.
- The existing bridges in this section were previously designed to accommodate the widening of AHD.
- Traffic volumes were monitored and analyzed and indicated that the widening was required. The engineering design for the widening of this portion of AHD started in 2018.
- Alberta Transportation is widening approximately 18 km of the South West Anthony Henday Drive, adding one lane in each direction.
- This will be constructed as one project from east of 111 Street to north of Whitemud Drive.
- The project was tendered in 2019, Carmacks Enterprise Ltd. is the successful prime contractor for the project.
- The contract includes:
– The widening of three bridge crossings at North Saskatchewan River, Wedgewood Creek and Whitemud Drive.
– The design and construction of two noise walls.
– The construction of ten maintenance accesses along Northwest Anthony Henday.
- Project got underway in Fall 2019 and will be open to traffic in Fall 2022.
TRAFFIC ACCOMMODATION STRATEGY
- The posted speed limit of 100 km/h on SWAHD will be reduced to 80 km/hr during construction.
- Work requiring lane closures, lane restrictions or additional speed reductions will not be allowed during the daytime.
- Due to the high traffic volume, Carmacks will conduct as many nighttime operations as possible. Hauling shall be restricted during peak commuter periods.
- For the purpose of North Saskatchewan River and Wedgewood Creek bridges, temporary paved median crossovers will be built and one lane traffic implemented for a set period of time.
- A full-time person has been appointed by Carmacks to continuously inspect and monitor the operation of all traffic control devices.
