Project Overview
The City of Caldwell is replacing the Kimball Bridge over Indian Creek in Caldwell. The current bridge is aging—the first part of it 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.
