On Thursday (Oct. 17), WSDOT contractor, Cascade Bridge LLC, will close both directions of SR 500 near Northeast 54th Avenue/Stapleton Street

VANCOUVER – Nighttime travelers who use State Route 500 in Vancouver should expect delays and use an alternate route.

On Thursday (Oct. 17), Washington State Department of Transportation contractor, Cascade Bridge LLC, will close both directions of SR 500 near Northeast 54th Avenue/Stapleton Street. During the closure, crews will work to set and brace the new girders, also known as bridge support beams. This work is part of the intersection improvements project that will construct a new pedestrian overcrossing that connects people who walk, bike or roll, on either side of the highway.

What to expect 

• From 9 p.m., Thursday, Oct. 17 until 5 a.m., Friday, Oct. 18: Both directions of SR 500 between St. Johns Boulevard and Northeast Andresen Road, near milepost 2.4, will be fully closed.
• A signed detour will guide people using SR 500 to exit the highway ahead of the closures:
  • Eastbound SR 500 travelers will be diverted at St. Johns Boulevard.
  • Westbound SR 500 travelers will be diverted at Northeast Andresen Road.

Because this work involves lifting heavy girders above the travel lanes of the highway to set them, it requires the full closure of SR 500 for safety, and travelers will need to use an alternate route. Travelers are reminded to slow down as they approach the work zone, follow directional detour signs and expect delays.
