Major work has begun on the construction of the Highway 11 interchange project. The work is part of the Fraser Valley Highway 1 Corridor Improvement Program, which includes widening Highway 1.

The project is the feature of Phase 3B of the overall widening program, with $2.65 billion in provincial funding, and is expected to be complete in 2031.

The replacement of the interchange at Highway 11 will accommodate increased traffic volumes by adding an additional lane in each direction, making travel easier throughout the region.

Work on Highway 1 will include widening 2.1 kilometres of the highway from McKenzie Road to just east of the Highway 11 Interchange. That work includes new HOV/EV lanes, as well as bus-on-shoulder lanes and an extension of the westbound truck climbing lane, improving traffic flow and transit efficiency.

Improvements will also be made to the intersections at Highway 11/Marshall Road and Highway 11/Delair Road. In addition, the project will enhance active-transportation connections, including multi-use paths, sidewalks and bike lanes.

The province announced in December 2025 the $242-million award for the design-build contract to Metro Vancouver (Infrastructure) Partnership, a joint venture between Hall Constructors, Jacob Bros. and EBC Inc.

As work on the corridor continues, two additional major-works contracts in Phase 3B will advance this year, including the contract for work on Mainline East. This contract has recently been awarded to Jakes Construction, based out of Chilliwack, for $118 million. The project will widen approximately 4.6 kilometres of Highway 1 and add HOV/EV and bus-on-shoulder lanes. Construction updates will be released later in the spring.
