Construction of the provincial HWY 1A/22 interchange project is officially underway! The project will improve the flow of traffic along the Highway 22 corridor and make both highways safer for all travelers.
*There have been a number of inquiries regarding the ability for emergency services to access the communities of Sunset Ridge, Heartland and Heritage Hills during construction and the associated heavy traffic volumes. Throughout construction, Cochrane Protective Services are engaged in regular project updates with the contractor and Alberta Transportation to ensure that emergency access is maintained for all communities as public safety is a top priority.

Alberta Transportation and Economic Corridors has provided the following update regarding traffic impacts:
September 9: Traffic shift
Alberta Transportation and Economic Corridors advises that a major traffic shift will occur this week as part of the Hwy 1A-22 interchange project:
The shift will begin the evening of Wednesday, September 11, and be completed overnight, with new lanes open for the Thursday morning commute. Traffic on Highway 22 will move to new pavement north of the temporary roundabout, rejoining the existing pavement near Ranche Road. The connection to the roundabout will change, and drivers should proceed with caution. A new ramp from westbound Highway 1A to northbound Highway 22 will also open, allowing traffic to bypass the temporary roundabout. The shift will happen in stages overnight, with brief traffic stoppages, and new signage will be in place to guide drivers. Closed sections of old pavement will be removed following the shift. Please drive carefully and be mindful of the new traffic setup.
August 30: Paving remedial work
Alberta Transportation and Economic Corridors advises that some of the detour paving work completed overnight Thursday requires continued remedial work on Friday. Drivers on Hwy 1A will be partially routed on a temporary gravel section of road near the Cochrane Ranche site through Friday afternoon. Crews will complete the remaining pavement work Friday evening, with Hwy 1A drivers routed back onto the finished detour overnight. We appreciate the continued patience of residents as this work is completed, and ask that all drivers be observant of construction zone signing, flagging and speed limits.
August 29: New road section opens
A section of the new road, from 6th Avenue to Big Hill Creek, will open overnight on August 29. All traffic on Highway 1A will be shifted onto this new section.
Beginning Friday morning, the temporary access by the bridges will be closed, and the permanent, paved access to the Historic Cochrane Ranche will be restored. Additionally, access to the parking lot will return to its permanent, paved location. The pedestrian detour will remain in its current location.August 22: Haul truck operations update
Crews will be hauling material across both the west and occasionally the south legs of the detour roundabout and continue into the fall. Crossings will be flagger controlled.
April 22: Haul truck operations begin
Crews will be hauling material across both the east and south legs of the detour roundabout and continue throughout the summer. Crossings will be flagger controlled.
