The Steveston Interchange project is a key part of the Highway 99 Tunnel Program to improve travel along the Highway 99 corridor. As part of the broader program, the new Steveston Interchange will improve connections for vehicles, transit users, pedestrians, and cyclists.
Opening in 2025, the modernized interchange will provide more vehicle lanes, improve transit operations, and include sidewalks and cycling lanes on both sides of the structure for the first time. The project includes replacing the existing two-lane interchange at Steveston Highway and Highway 99 with a five-lane structure. The new structure will include two eastbound lanes and three westbound lanes, including a left-turn lane onto Highway 99, to improve traffic flow. Improved ramp connections between Steveston Highway and Highway 99 to improve traffic flow and reduce queuing for vehicles.
There are several transit-priority measures to allow buses to move through the interchange more efficiently, including signal priority at intersections, and a dedicated transit lane and in-lane bus stop in the northbound offramp.
As of June 2023 DMD has completed the design for the lighting signals and ITS system for the interchange. Key elements included design electrical, lighting, signals and ITS systems modification to the existing ITS and counterflow system, interface with BC Ministry of Transportation, TI Corp and the City of Richmond.
