Beginning Tuesday, Dec. 23, 2025, all five lanes of the new Steveston interchange at Highway 99 will be open, supporting better connections for commuters in Richmond and improving travel times along Highway 99.

The new Steveston interchange has three westbound lanes and two eastbound lanes in service, adding capacity to the crossing over Highway 99, and improving the flow of east-west traffic.

The new overpass will also improve travel times to and from communities south of the Fraser River by significantly reducing backups in the northbound off-ramp lanes on Highway 99. Once the new tunnel is open, southbound backlogs will also see major reductions.

While this marks the end of major construction, work will continue through spring 2026 to complete landscaping, on- and off-ramp paving, and other roadwork activities related to the final completion of the project.

The $87.5-million Steveston Interchange Project is a major piece of the Province’s Highway 99 Tunnel Program and was delivered on time and on budget. Other improvements to Highway 99 have been completed, including bus-on-shoulder lane extensions south of the tunnel, a transit connection from Bridgeport Road to Highway 99 southbound and cycling improvements at Highway 17A.
