About MDT's Bridge Management and Design Process

The MDT Bridge Bureau is tasked with keeping Montana's bridges safe, resilient, economical, and reliable. The Bridge Bureau has two sections: Bridge Management and Bridge Design.

The Bridge Management section inspects and maintains over 5,000 bridges throughout the state and guides maintenance for local agencies and jurisdictions. The Bridge Management section is responsible for conducting all inspections and evaluating needed repairs. Routine inspections are preformed every two years. In-depth inspections occur on specific and critical bridge components as needed to ensure that the most important components of the bridge are in good working condition.

The Bridge Design section provides design and engineering management on bridge replacement, rehabilitation, and preservation projects. They also establish and maintain design criteria and standards, participate in research projects, and promote design initiatives to improve bridge performance and value.
