SR 501 - I-5 to Port of Vancouver - Intersection and Profile Improvements

Project overview

Currently, oversized freight traffic must divert from this section of Mill Plain Boulevard (SR 501) onto city streets due to high points in the roadway and limited overhead clearances. Corridor modifications will increase safety along the corridor for all modes of transportation. Improvements will include reconstruction of two intersections (Washington/Mill Plain and Main Street/Mill Plain) and the replacement of three signal systems on Mill Plain (Columbia, Broadway and Main Street).

Pedestrian and bicycle features will also be added including upgraded pedestrian ramps to current ADA standards, buffered bike lanes, wider sidewalks to accommodate a shared use path and new crossing signals.

What to expect

In summer 2021, in coordination with the City of Vancouver, WSDOT's contractor, Granite Construction will begin work to pave sections of along Mill Plain Boulevard (SR 501) between the Port of Vancouver and Fort Vancouver, west of I-5. 

Travelers should expect daytime and nighttime delays in downtown Vancouver when traveling on Mill Plain Boulevard (State Route 501) and East 15th Street between Fort Vancouver Way, just west of I-5, and West 26th Avenue near the Port of Vancouver for roadway improvements this summer. Travelers may also encounter sidewalk closures in the area. 

Travelers should watch for signed detours directing them around construction. 

Oversized freight traffic must divert from this section of Mill Plain Boulevard (SR 501) onto city streets due to curves in the roadway and limited overhead clearances.

This project will remove high points in the roadway, reconstruct traffic signals to improve mobility for large freight vehicles and increase safety along the corridor for all travelers.
