Highway 1A Improvements



The Highway 1A improvements Project is a long-awaited upgrade to the Highway 1A corridor through Cochrane from east of Centre Avenue to west of Fifth Avenue. The project includes: 

  • widening from two lanes to four lanes from east of Centre Avenue to west of Fifth Avenue
  • realignment of Fourth Ave to Fifth Ave
  • new access, parking and turning lanes for Sixth Ave W businesses
  • improved pedestrian network with a new sidewalk and a paved multi-use pathway


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.

    With the construction season coming to a close, you may be wondering what the highway will look like as we wrap up work for the year.

    -  4 lanes of traffic on Hwy 1A will be opened east of 4th Ave to the Big Hill

    -  2 lanes of traffic on Hwy 1A will be open west of 4th Ave

    -   Both Hwy 1A intersections at 4th Ave and 5th Ave will be open over the winter

    -   The speed limit through town will revert to 50 km/h from 30 km/h

    -   The speed limit heading down the big hill will remain unchanged at 60km/h

    Work on the 4th Ave wall will continue through the winter and the new pedestrian pathways will be open and cleared of snow.

    The progress that has been made to this point has enhanced traffic flow through Cochrane and will continue to increase community connectivity. 

    This major project has had an impact on everyone in the community; thank you for your patience and understanding, Cochrane.  Illustration of work completed
