Signal Detection Upgrades


Design phase 

Updated: March 28, 2023

Reducing wait times and improving safety 

Reliable and accurate vehicle detection is required for proper traffic signal operation, to minimize vehicle delay and improve safety. We will replace traffic signal video detection systems at six intersections due to failing equipment and equipment no longer supported by the vendor. 
Video detection will be upgraded at the following intersections: 

  • 172nd Ave and Rock Creek
  • Otty Road and Fuller Road
  • Monterey Ave and 85th Ave
  • Stafford Road and Ek Road
  • Park Ave and 27th Ave


To maintain reliable signal operations, reduce wait times and provide safer roadways for all users.


  • Design: January 2023 to August 2023
  • Construction: Fall 2023 to Summer 2024

Traffic impact

Expect shoulder and lane closures with minimal delays during construction.

Current activities
