TRPC backs continued funding for Nisqually River Bridge project 

The Thurston Regional Planning Council (TRPC) approved legislative priorities for 2027, focusing on continued funding for the Nisqually River Bridge project.  

TRPC is advocating for $37 million in state funding for the 2027–29 to continue environmental review, technical studies and preparations needed to move the project toward a future design-build contract.  

The Washington State Department of Transportation has funding for the project in the current biennium, which ends in June 2027.  

However, funding for the next biennium is currently listed at zero, according to TRPC Senior Planner Veronica Jarvis.  

The project would improve the Interstate 5 crossing by addressing flooding and stability concerns, removing a fish passage barrier, improving stormwater treatment, adding a shared use path, and constructing a new crossing over the BNSF railway. 

Several design options are under consideration, including bridges approximately 6,000 and 12,000 feet long.  

At a TRPC meeting on Oct. 2, Jarvis described the Nisqually Bridge as a critical transportation artery for the region. She said traffic disruptions at the bridge can make it difficult for people to travel into and out of the area.  

Early work, including environmental studies, is already underway. Jarvis said continued funding would help maintain momentum and avoid potential delays, duplicated work and higher costs if the project is put on hold.  

Coalition 

Other regional stakeholders support the funding effort. The South Sound Military Communities Partnership has identified the Nisqually Bridge as its top legislative priority.  

TRPC Executive Director Elissa Gertler said the organization has also discussed Interstate 5 transportation issues with the Puget Sound Regional Council and Portland Metro.

Regional officials are considering a broader coalition because improvements in one part of the corridor can shift congestion and problems to another area.  

TRPC plans to continue outreach to other jurisdictions and transportation organizations as part of its legislative advocacy.
