Partial Grade-Separated Option B (PGSB) Identified as the Preferred Alternative

July 2018

Cowlitz County, Washington State Department of Transportation, and the Federal Highway Administration are studying ways to address traffic congestion, travel reliability, and safety issues at one of the busiest truck tonnage intersections in our state – Industrial Way (State Route 432), State Route 433, and Oregon Way.

The Project’s Executive Committee reviewed the environmental analysis of the two “build” alternatives and the “no-build” alternative presented in the Draft Environmental Impact Statement (EIS) and the public comments received at the March 20th public hearing and during the Draft EIS public comment period. Following this review, the Executive Committee identified the Partial Grade-Separated Option B (PGSB) as the Preferred Alternative. This recommendation will be documented in the Final EIS, and the Federal Highway Administration’s final selection of a preferred alternative will be documented in the project’s Record of Decision.

Preferred Alternative: Partial Grade-Separated Option B (PGSB)

Key advantages of the PGSB Alternative:

  • Substantial improvement in traffic operations (50-60% reduction in vehicle delay and congestion)
  • Better access to commercial and industrial properties
  • Critical emergency service routes not blocked when trains cross
  • No residential displacements

Key design features of the PGSB Alternative:

  • Elevates most traffic movements to avoid traffic delays when trains cross (elevated structure shown in grey on the graphic)
  • Provides a surface (at-grade) roundabout for east-west through movements on Industrial Way and local circulation (at-grade surface improvements shown in purple on the graphic)
  • Adds pedestrian facilities, including sidewalks and a new multi-use path for north/south connectivity
  • Improves 14th Avenue to a two-way local street between Alabama Street and Beech Street
  • Reconstructs West Port Way and East Port Way as a one-way loop road
  • Does not realign the existing railroad line, avoiding closure of Oregon Way during project construction

Upcoming Work

The project team is working on preparing a Final EIS, which will disclose anticipated impacts and benefits of the project, identify mitigation measures, and include responses to comments received on the Draft EIS. Publication of the Final EIS is anticipated in late 2018.
