Project Overview

The MT 200 Bridges Lewistown Area project will reconstruct a series of 10 bridges along US 87/MT 200 in the Lewistown area. The project will replace aging and deteriorating structures in fair and poor condition with new bridges or culverts. Nine of the bridges were constructed prior to 1940 and the timber structures are reaching the end of their useful and serviceable life.

In addition to the bridge replacements, the project will include minor road and approach construction to tie the new structures into the existing road. Safety components including wider shoulders, new guardrail and rumble strips are also included in the project design.

Construction is planned to begin in spring of 2025; however, this is dependent on weather and other unforeseen factors.
