LEWISTON, ID – The Idaho Transportation Board has identified the US-95 Spalding Bridge east of Lewiston for future construction funding under the state’s Transportation Expansion and Congestion Mitigation (TECM) program, advancing plans to replace the aging structure and expand capacity at a major highway interchange.
During its regular monthly meeting on Thursday, the board approved recommendations prioritizing several transportation corridors across Idaho, including the Spalding Bridge project, which had already begun design work under earlier TECM funding.
The new funding is made possible by House Bill 25, passed by the Idaho Legislature earlier this year, which adds $20 million annually to the TECM fund for the next three years. The legislation enables the Idaho Transportation Department (ITD) to invest an additional $1 billion into the state’s highway system.
Prior to the bill’s passage, there was no funding available for construction of the Spalding Bridge project. With this update, construction could begin as early as 2028. The project will replace the current bridge with two wider spans and improve the US-95 and US-12 interchange to address growing traffic demands and enhance safety.

The project will be included in the draft Idaho Transportation Investment Program (ITIP) for 2026-2032. The public will have an opportunity to comment on the draft ITIP, including the Spalding Bridge proposal, during a statewide review period in July. Final approval of the program is expected in September.
The board’s decision continues a broader initiative to relieve congestion and improve infrastructure in high-priority areas. In north-central Idaho, TECM funding has also been used to begin work on the nearby Arrow Bridge project.
