Preparation of Technical Studies and Draft Environmental Impact Statement Underway

October 2017

Cowlitz County, in cooperation with the Washington State Department of Transportation and the Federal Highway Administration, is studying ways to address traffic congestion, travel reliability for vehicles, emergency response, freight truck mobility, 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 team is continuing to conduct detailed technical studies on the two “build” alternatives (intersection reconstructed) and the “no-build” alternative (intersection not reconstructed) advanced to the Draft Environmental Impact Statement (EIS). The studies being conducted include evaluating the impacts on the built environment (such as traffic, emergency access, residents, businesses, park and recreation, cultural resources, and noise) and the natural environment (such as wetlands, floodplains, fish, and wildlife). To view and read a description of the two build alternatives advanced to the Draft EIS and their contrasting design features please visit or the Longview Public Library, or call 360-577-3030 to request a copy.

Upcoming Work

The project team is preparing a Draft EIS to disclose the anticipated impacts and benefits resulting from each of the alternatives and to identify mitigation measures. Publication of the Draft EIS is anticipated in Winter 2018 followed by a 45-day public comment period with a Public Hearing/Open House in early Spring 2018.
