The St. John’s Blvd Interchange Project replaced the signalized intersection at SR-500 and St. Johns Blvd located in Vancouver, Washington, with a freeway-style interchange. Work consisted of raising the St. Johns Blvd roadway by 25 feet along with construction of a new bridge and interchange that connected SR-500 to St. Johns Blvd. Construction included around a mile of improvements along SR-500 that included: clearing and grubbing, excavation and grading, storm drainage system, crushed surfacing, hot mix asphalt (HMA) paving, bridges, pavement, traffic signals, illumination, signing and landscaping. Crews performed work in tight workspaces which was a challenge at times, many small walls had to be installed around existing traffic. Due to high volume traffic in the work zone creating tight workspaces, complex traffic control measures were taken to ensure roadway safety such as installing small walls along the delineation zone. With the dedication of our team, both lanes along SR-500 were able to stay open for traffic throughout the project, minimizing the overall impact to the traveling public for the two-year project duration.
