  • Aug 27: The shallow utility work required for the Hwy 1A improvement project will take place this week initiating one evening road closure on Hwy 1A from Centre Ave to 4th Ave on Fri, Aug 27 at 9pm - Sat morning at 7am. 
  • Aug 23: Starting Aug 24, water main replacement will commence along the east side of Centre Avenue from Hwy 1A through to Powel Street.

    The work will require the closure of the righthand, south bound lane for the next week.  Following completion of the water main work, both southbound lanes will be detoured onto First Avenue West though to First Street West to facilitate storm water upgrades – more details to follow. During this phase of construction, alternate routes, such as Fourth Avenue West or Fifth Avenue West should be considered to access the Quarry and other shopping areas in the downtown.

  • Aug 2: Work starts on Centre Ave early this week. This includes detouring southbound traffic on Centre Avenue onto First Avenue West and then onto First Street West back to Centre Avenue. Motorists should anticipate traffic delays and are asked to reduce speeds and use extra caution. 
  • Jul 23: Construction of deep utility crossings beneath the highway were successfully completed during overnight shifts and the nightly detour though downtown is no longer in effect. The next step in the project is to prepare for the utility upgrades beneath Centre Ave between HWY 1A and Powel St. In coming weeks, this will include a new detour for southbound traffic on Centre Ave. Further details will be shared prior to the detour being initiated. Plans are underway to demolish the old KFC building located at the corner of HWY 1A and Centre Ave.
  • Jul 16: The deep utility replacement work (water, sanitary and storm) required for the Hwy 1A improvement project will take place this week initiating four temporary evening road closures on Hwy 1A from Centre Ave to 4th Ave.
  • Jul 10: Motorists should anticipate traffic delays in the area as construction starts on the north shoulder of the highway. The highway will be reduced to 2 lanes through the work area. This will be in place until construction wraps up in the late fall.
  • Jul 8: Top soil and tree stumps are being removed to support the start of construction.
  • Jun 22: Work on the HWY 1A improvement project starts: Parking lot at the corner of Centre Ave and HWY 1A will be closed, as well as First Ave between Centre Ave and 2nd St. Construction fencing will be installed, please follow construction signage.

BACKGROUND

Widening highway 1A has long been a priority for both the Province and Town of Cochrane and is an important piece of Cochrane’s Traffic Plan. This project was approved in the fall of 2020, as Council recognized an opportunity to utilize Provincial grant funding to support these roadway improvements. 

When complete, it will provide a much-needed improvement to the highway corridor that is experiencing heavy congestion for both local and regional users. The project will also include additional pathways and crosswalks, ensuring a safer experience for vehicles, pedestrians and cyclists.
