Intersection changes and new traffic signals

Intersection improvements
Starting at the end of July, Strathcona County will be constructing new intersection features to improve safety for pedestrians and traffic efficiency. These improvements will occur at eight locations in Sherwood Park.

New traffic signals
Two new traffic signals on Wye Road at Nottingham Way and Estate Drive are required to maintain safety while supporting efficient traffic movement through the corridor.  They will be activated once Wye Road improvements are completed.

Strathcona County relies on state-of-the-art technology to keep traffic moving smoothly. Traffic engineers and technologists operate and monitor traffic flows using specialized traffic analysis software, advance traffic management systems, video detection equipment, and traffic control devices.

Although traffic signals may seem simple, in reality, their management and operation are very complex. Small changes in one part of the transportation network impacts other areas; therefore, decisions made in traffic signal operation must consider all road users. 

There are approximately 88 traffic signals that Strathcona County owns and operates.

The Planning, Engineering and Safety branch of Transportation Planning and Engineering oversees the design and construction of the County's traffic signals while the Right-of-Way Management branch of Transportation and Agriculture Services manages the operation and maintenance of the County's traffic signals.

Intersection improvements

New intersection features will be constructed in 2020 to improve safety for pedestrians and traffic efficiency. Benefits of these changes include reduced wait times for pedestrians and drivers and increased pedestrian cross safety. 

Construction is expected to be complete by September 30, pending weather and unforeseen issues. 

  • Lakeland Drive (Petroleum Way) and Broadmoor Boulevard - install a new concrete island to close outside left turn lane for improved signal efficiency. 
  • Baseline Road and Shivam Boulevard (Chippewa Road) - install a new concrete island to close outside left turn lane for improved signal efficiency. 
  • Davidson Drive and Clover Bar Road - install a new traffic island for reduced pedestrian crossing distance; and the addition of a dedicated right turn and signal timing improvements  
  • Clover Bar Road and Heritage Drive -  install a new traffic island for reduced pedestrian crossing distance; and the addition of a dedicated right turn and signal timing improvements   
  • Emerald Drive and Ellesmere Drive - install a new traffic island for reduced pedestrian crossing distance; and the addition of a dedicated right turn and signal timing improvements  
  • Emerald Drive and Eton Boulevard – reconstruct pedestrian ramps for improved alignment with pedestrian crosswalk  
  • Lakeland Drive and Sherwood Drive - modify the existing concrete median for improved vehicle turning movement 
  • Baseline Road and Broadview Drive - reconstruct pedestrian ramps for improved alignment with pedestrian crosswalk. 

Left-turn lane changes

Two vehicles driving through dual turning lane.

At several County intersections, you will notice that dual left-turn lanes have been changed to single lanes. Drivers turning left at these intersections will now be able to do so for the duration of a green light, instead of during a green arrow light only.   

As seen in the photo above, when two vehicles are turning at the same time, sightlines can be restricted. Consequently, collisions in dual left-turn lanes are more frequent and severe than in single turn lanes.

In Strathcona County, there are several intersections that have less traffic volume and do not warrant double left-turn bays at this time.

By changing these intersections to single-lane only left turns with protected permissive signals (green arrow and green ball lights), we can defer the need to install protected only (green arrow only) left turn signals in order to maintain the efficiency of traffic flow and reduce wait times. These intersections will be monitored to ensure results are as expected.

The County will continue to upgrade the left turn signals to “protected only” for remaining locations with dual left-turn lanes.
