Alberta's 2025 construction season delivered major upgrades to Deerfoot Trail, as well as more than 100 road and bridge projects across the province.

Alberta has a vast provincial highway network including more than 64,000 lane kilometres of highways and almost 4,800 bridge structures. The capital plan invests nearly $8.5 billion in 376 municipal projects and 500 provincial projects for a total of 876 projects across the province.

Work on Deerfoot Trail advanced significantly this year with the completion of the McKnight Boulevard NE and 16 Avenue NE projects. These upgrades will enhance road safety, improve access to essential services. They now save up to 20 minutes of travel time for Calgary drivers.

The McKnight Boulevard project added a fourth lane in each direction between 32 Avenue NE and Beddington Trail NW. The 16 Avenue NE project also added a fourth lane in both directions from Memorial Drive to 32 Avenue NE, helping reduce congestion and improve traffic flow.

"Deerfoot Trail is the busiest highway in Alberta, but it's only one piece of a much bigger picture. From the new interchange in Leduc, to twinning on highways 3, 11, 40 and 63, to bridge renewals in the Peace Region - our construction season delivered meaningful results for Albertans. These hundreds of projects are shaping our future transportation network by easing congestion, improving safety and supporting a thriving economy." Devin Dreeshen, Minister of Transportation and Economic Corridors Southern Alberta

The 2025 construction season delivered major progress in southern Alberta, including the ongoing twinning of Highway 3 between Taber and Burdett, where 46 kilometres of new eastbound lanes, intersection upgrades, range road improvements and the Grassy Lake bypass are all moving forward.

Almost 118 kilometres of highways were paved this season, along with multiple bridge deck replacements, improving safety and reliability throughout the region. The Highway 1A/22 Cochrane Interchange also opened in 2025, improving traffic flow and supporting future growth. Central Alberta

Work continued on the twinning of Highway 11 between Sylvan Lake and Rocky Mountain House, a key route for recreation, commerce and tourism. Two phases are now complete, with design underway for the remaining sections. The region also saw almost $63.5 million in new paving projects across more than 175 kilometres of highways, along with new roundabouts east of Camrose and on Highway 42. Peace Region

The Peace Region reached a major milestone with the twinning of 10 kilometres of Highway 40 south of Grande Prairie. The work also included bridge improvements, slide remediation, a vehicle inspection station and a new roundabout. Bridge rehabilitations and truss replacements along Highway 88 also strengthened a critical northern transportation corridor. North Central Region

In north central Alberta, upgrades to Terwillegar Drive increased traffic capacity and improved flow on one of Edmonton's busiest roads. Additionally, the new QEII and 65 Avenue interchange in Leduc is now open, improving access to the Edmonton International Airport and relieving pressure on Highway 2. Work also progressed on twinning Highway 63 north of Fort McMurray, and on Highway 881 safety upgrades, including new passing lanes, rest areas and roadside upgrades.
