Project Overview
The Kimball Bridge project is being led by the Local Highway Technical Assistance Council (LHTAC). LHTAC acts as a link between local cities, counties, highway districts and the Idaho Transportation Department, helping local agencies access and use federal and state-aid highway funds.
The current bridge is aging and needs to be replaced. The first part of the bridge was constructed in the 1930s and the second was constructed in the 1970s. The new bridge is expected to serve the City of Caldwell for many years to come.
The Kimball Bridge Project is a state funded project for $4 Million dollars.
