The Montana Department of Transportation is using online meetings and presentations to engage with the public rather than in-person meetings due to community health and safety concerns during the COVID-19 pandemic. MDT together with its construction contracting partners, continue to take the COVID-19 pandemic very seriously. Construction projects on Montana's roads and bridges are considered an "essential" operation and will continue moving forward as scheduled. For more information visit

Project Overview

The Montana Department of Transportation is evaluating 11 bridges on MT 37 between Libby and Eureka. The bridges are aging and in need of repairs and routine upkeep. Most of the bridges were built between 1959 and 1974. They are safe to drive on, but it is important to identify needed repairs to keep them safe and functional. Just like an oil change for your car, routine upkeep of the bridges extends their service life and ensures Montanans receive the best return on our bridge investments.

The evaluations will allow MDT to determine and prioritize the needed repairs and will include:

  • Testing the bridge decks (driving surface) to evaluate the current condition.
  • Verifying inspection reports and repair lists.
  • Gathering input from local maintenance staff on individual bridge issues.

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.
