I 90 Bridges East of Alberton project logo

Project Overview

The Montana Department of Transportation (MDT) and Frontier West are rehabilitating two bridges that carry Interstate 90 (I 90) over the Clark Fork River east of Alberton. The bridges include the westbound bridge located 5 miles east of Alberton and the bridge located 6 miles east of Alberton that carries both east and westbound traffic. These bridges were originally built in the early 1960s and need repairs. This project will extend the service life of these bridges.

Improvements include:

  • Replacing the concrete bridge deck on the eastbound portion of the 6-mile bridge.
  • Painting portions of the steel superstructures to slow corrosion.
  • Replacing bridge joints and damaged bearings.
  • Repairing bridge girders.
  • Upgrading bridge drainage and guardrails.
  • Resurfacing the pavement approaches on each end of the bridges.
  • Replacing the shoulder rumble strips and pavement striping.

Stay Informed During Construction

Communication with the public is important to MDT and the success of the project. The community will be notified about construction and traffic activities, at key project milestones throughout the construction process. MDT will notify the public through the project website, local media, mailings, social media, and email and text notifications.

Current construction information and road conditions can be found on the MDT Travel Info App.
