Today at its regular monthly meeting the Idaho Transportation Board accepted staff recommendations on priority corridors across Idaho using TECM funds to address congestion, including the Spalding Bridge on U.S. Highway 95 east of Lewiston. Since Transportation Expansion and Congestion Mitigation funds were first used by the department for bonding and advancing major projects in 2022, ITD has delivered timely construction of expansion projects across the state. Today’s actions are a continuation of that.
Funding came from House Bill 25, which was passed by the Idaho Legislature earlier this year. The legislation provides an additional $20 million a year to the Transportation Expansion and Congestion Mitigation fund for the next three years and allows the department to invest an extra $1 billion in the Idaho transportation system.
Prior to House Bill 25, no funding was available for construction; now it could begin at the earliest in 2028. This project will replace the existing Spalding Bridge with two wider bridges and add capacity to the existing US-95 and US-12 Interchange.
With this project now included in the draft Idaho Transportation Investment Program (ITIP), the public will have the opportunity to give feedback on this project and the department’s full list of planned projects from 2026-2032 during the annual comment period in July. Then the draft ITIP will be presented to the board for approval in September.
The board’s action today reflects continued investment targeting congestion and capacity in major corridors that were previously funded by TECM bonds as authorized by the Idaho Legislature. In North-central Idaho, TECM funds had previously allowed ITD to start design of this bridge and the nearby Arrow Bridge.
This project and others were identified because they are existing high-priority corridor needs that will improve traffic flow and increase safety.
