Overview

Off-system bridges are not on the state highway system and are typically owned and maintained by local governments. In 2023 the Montana Legislature made a one-time allocation of $100 million to help local governments address the crisis of deteriorating off-system bridges, secondary highways, and urban routes. These funds have been used to repair or replace 150 county bridges, impacting 50 of Montana’s 56 counties.

MDT is administering the replacement of 24 bridges that were identified in partnership with the Montana Association of Counties under the Off-System Bridge Prioritization Program. These bridges include:
