Caldwell Kimball Bridge Replacement Over Indian Creek Now Set for Summer 2027

CALDWELL — The Kimball Bridge replacement over Indian Creek in downtown Caldwell, Idaho, will take longer than planned. Construction began in February 2026 and is now expected to be complete in summer 2027, according to the City of Caldwell's project page, updated Nov. 4, 2026. The Kimball Bridge project was previously expected to wrap up in late 2026.

The current bridge is aging. Its first section was built in the 1930s and the second in the 1970s, and the new bridge is expected to serve Caldwell for many years, the city says. The Kimball Bridge project is a $4 million state-funded project led by the Local Highway Technical Assistance Council (LHTAC), which helps cities, counties and highway districts use federal and state highway funds.

Why the Kimball Bridge project slipped

The city lists several issues behind the delay. Bridge demolition was slower and more complex than expected. Utility conflicts turned up in the project area, including a communication trunk line that cannot be relocated. Crews found buried obstructions that were not expected, so part of the project had to be redesigned. And next to the work zone, a new building went up while existing buildings needed unexpected support measures. The Idaho Press also published a city photo showing Indian Creek water filling in under the bridge because existing gabion walls were leaking.

The city says it is working closely with LHTAC and the contractor to help get the bridge finished.

What to expect downtown

Kimball Avenue is closed between Blaine Street and Arthur Street, with drivers and pedestrians detoured. Expect lane and parking closures on Blaine Street, restricted street parking in the project area and occasional daytime noise. Downtown businesses remain open, and there are several ways to reach Indian Creek Plaza. Project updates are available through the city's sign-up page, and questions can go to the project team at the contact on the original listing or 208-377-9688.
