What is the Project?


The SR 432 Rail Realignment and Highway Improvements Project will identify project concepts to address the safety, traffic congestion, system mobility and freight capacity issues where the rail and roadway systems overlap along the corridor. These improvements will 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.

What's New

POSTED 11.14.13 The initial project concepts presented at the first public open house on November 13, 2013 are now available. A copy of the open house presentation and the initial concepts can be downloaded from the document library.

POSTED 09.24.13 An Elected / Agency Officials Briefing was held on September 18,2013. Meeting materials are available for download from the document library.

Get Involved

The first public open house was held on November 13, 2013 to introduce the project and initial concepts to address safety, congestion, efficiency, system mobility, and freight capacity issues throughout the SR 432 corridor and to gather input on important criteria to consider as concepts are screened.

Another open house will be held in spring of 2014 to report back to the community on the range of projects throughout the corridor moving forward to Phase II for more environmental study and refinement. Additional opportunities for public input will occur as the project moves forward. The project website will provide the latest available information.
