The Steveston Interchange Project will result in a new interchange structure that will accommodate two eastbound lanes and three westbound lanes (including a left turn lane), as well as improved connections to and from the overpass for vehicles, pedestrians, and cyclists. The new interchange will replace the existing two-lane overpass structure at Steveston Highway and Highway 99. It will improve local travel in this area of Richmond and enhance access to and from Highway 99. The Steveston Interchange Project also complements the future new George Massey Crossing, and represents part of the related corridor improvements associated with this future major project.
