Mount Lehman Interchange on B.C.’s Hwy. 1 to be expanded to five lanes

BC’s Ministry of Transportation and Transit announced that as part of the broader project to widen Highway 1 through the Fraser Valley, the Mount Lehman Road Interchange will be widend from three to five lanes, to more easily connect Abbotsford to the Fraser Highway and Abbotsford International Airport.

“Expanding the Mount Lehman Road Interchange is about more than improving the road, it’s helping families in the Fraser Valley get home safer, spend less time in traffic and more time together,” said Mike Farnworth, Minister of Transportation and Transit. “As we continue widening Highway 1, we’re not only making travel faster, we’re also creating good jobs for people right here in their own communities, strengthening our economy and keeping people and goods moving.”

The Mount Lehman Road Interchange project includes:

• widening the existing structure from three lanes to five lanes, including a new southbound lane and a new northbound-to-westbound left-turn lane
• adding a new multi-use path on the east side of the structure to improve pedestrian and active transportation options, and connecting this to a new multi-use path parallel to Highway 1
• seismic upgrades to enhance safety and resilience
• approximately 3.5 kilometres of widening on Highway 1

“As Abbotsford continues to grow, improvements to the Mount Lehman Interchange are critical to keeping people and goods moving safely and efficiently,” said Ross Siemens, mayor of Abbotsford. “By reducing congestion and improving reliability along this key corridor, we support the efficient flow of goods and services that local businesses and the regional economy rely on, while also helping residents and families travel more easily to work, school and community activities. Investments like this help build a safer, more connected and economically resilient Abbotsford, today and into the future.”

Starting as early as Monday, March 9, 2026, traffic on the Mount Lehman structure will be reduced from three lanes to two lanes, with one lane in each direction, to accommodate construction of the wider structure. The lane reduction is anticipated to remain in place until the end of 2026.
