SR 432 Highway Improvements and Rail Realignment Study
The SR 432 Highway Improvements and Rail Realignment Study is complete. For a copy of this and related documents, please visit: SR 432 Highway Improvements and Rail Realignment Study or contact CWCOG at 360-577-3041.
The SR 432 Highway Improvements and Rail Realignment Study was completed in the fall of 2014. It identified various project concepts to address safety, traffic congestion, system mobility and freight capacity issues where the rail and roadway systems overlap along the SR 432 industrial corridor. Once constructed, these improvements will improve safety and facilitate regional economic development by keeping freight, employees, residents, and tourists moving through the corridor.
In 1988, the Lower Columbia ports requested that the U.S. Army Corps of Engineers study the deepening of the Columbia River shipping channel to help the region become competitive in the global marketplace. The river deepening increased interest in moving freight through the region, leading to further study of the road and rail systems that connect to the Columbia River and the Port of Longview in order to handle increasing volumes of freight.
The following jurisdictions partnered on theSR 432 Highway Improvements and Rail Realignment Study:
- Cowlitz-Wahkiakum Council of Governments (CWCOG)
- City of Kelso
- City of Longview
- Cowlitz County
- Cowlitz Economic Development Council (CEDC)
- Port of Longview
- Washington State Department of Transportation (WSDOT)
The CWCOG led this partnership while working closely with WSDOT, the Federal Highway Administration, other regulatory agencies, BNSF Railway, and the public.
Various design concepts were developed and evaluated for rail and highway improvements throughout the SR 432 corridor to improve safety, mobility, congestion, and freight capacity. The top concept that emerged from this study was a Grade Separated Intersection at SR 432/SR 433. Cowlitz County is the lead agency for the engineering phase of this project.
- The SR 432 Realignment Feasibility Study is complete and the report published.

State Route 432, located in the Longview/Kelso/Rainer Urban area is approximately 10.3 miles in length and provides a variety of vital transportation functions. This route serves as a major industrial transportation corridor, connecting the Port of Longview, the city of Longview and city of Kelso industrial areas to major markets via Interstate 5.
Why is WSDOT Studying the State Route 432 Longview Industrial Corridor?
A Route Development Plan (RDP) on SR 432 was completed in 2001. The RDP was completed by the Cowlitz-Wahkiakum Council of Governments (CWCOG), the Metropolitan Planning Organization for the Longview-Kelso Urban Area, and the Washington State Department of Transportation (WSDOT). The plan identified a series of improvements over 20 years to enhance the overall transportation system in the area.
WSDOT completed a technical report and preliminary feasibility analysis for realignment and improvements to the highway and rail facilities in the SR 432 Longview Industrial Corridor.
The End Result
The technical report and preliminary feasibility analysis developed recommendations to improve rail and freight movement throughout the SR 432 Longview Industrial Corridor. The study also reviewed the feasibility of constructing a limited access bypass highway to reduce future rail/truck conflict in the corridor.
The feasibility analysis:
- Identified specific improvements to highway and rail facilities in the corridor.
- Assessed the viability of a new roadway and rail alignment to better serve the SR 432 corridor.
- Recommended an implementation strategy identifying potential funding sources, project timeline and improvement phases, and the projected improvements cost.
What is the project timeline?
The study has been completed and the report published in 2009.

A State appropriation was provided to study the feasibility of a highway and rail realignment project in the Longview Industrial Area (SR 432) corridor, specifically, whether a limited access bypass highway is a feasible solution to reduce future rail/truck conflicts.
