Needs & benefits

Why is WSDOT making corridor modifications on Mill Plain Boulevard (SR 501) between the Port of Vancouver and I-5?

Currently, oversized freight traffic must divert from this section of 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 should people expect?

The project includes two construction projects and timelines.

  • Paving from Fort Vancouver Way to West 26th Avenue will occur during the summers of 2020 and 2021. The paving project will include corridor restriping to accommodate bicycle improvements. The majority of the paving project work will be completed at night.
  • Intersection Improvements will occur between the summer and fall 2020 and will include the removal of high points in the roadway, reconstruction of traffic signals to improve mobility for large freight vehicles and increased safety along the corridor for all modes of transportation. Trees causing damage to the roadway and sidewalks will be removed during construction and replaced by the City of Vancouver. The intersection improvement work will be performed at night and during the day.

During construction in summer 2020, travelers will need to plan around closures and detours. Impacts will be communicated in advance of construction in spring 2020.

Public Involvement 

On Wednesday, Oct. 23, 2019, approximately 150 joined WSDOT, the city of Vancouver, C-TRAN and the Port of Vancouver at an open house to learn about this project.

Project Benefits

  • Freight mobility: Corridor modifications will help keep traffic and freight moving through this vital stretch of roadway and decrease freight traffic on local streets.
  • Safety: The project will address mobility and safety for all users: people driving, people walking or using assistive devices, and/or people using bicycles.
  • Economic: Although some parking losses are anticipated (approximately 15 spaces or two to three per block), the overall improvements will help meet the needs of future development in the area.
  • Environmental: Approximately 30 trees causing damage to the roadway and sidewalks will be removed during construction and replaced by the City of Vancouver. Tree removal is necessary to implement the required safety and freight mobility improvements. Tree removal will be done in accordance with all applicable City urban forestry regulations.

The End Result
Corridor modifications will help keep traffic and freight moving through this vital stretch of roadway.

Timeline

  • Spring 2019 - Spring 2020: Design and continued outreach.
  • Summer 2020: Construction Begins
