Deer Lodge Area Bridges Rehabilitation

Project Overview

The Montana Department of Transportation (MDT) plans to rehabilitate 11 bridges along the I 90 corridor between 5 and 20 miles south of Deer Lodge in Powell and Deer Lodge counties to maintain long-term traffic flow and incorporate safety improvements. Construction is scheduled to begin on April 18, 2022, weather permitting, and take approximately five months. Detailed project information can be found in this Fact Sheet, and regular updates will be posted on this website.

The surfaces on these bridges were part of the original construction of I 90 more than five decades ago. The rehabilitation and improvements are essential to extend their service life, and will include repairs to deck and substructure concrete, deck milling with a concrete overlay and crack sealing, guardrail replacements, and other upgrades.

Traffic delays during construction will be kept to a minimum. Both eastbound and westbound I 90 through Deer Lodge and Powell counties will remain open at all times, with single lane bridge closures during construction. Deer Lodge Area Bridges Rehabilitation

I90 to Anaconda MT1 Pavement Preservation

Project Overview

The Montana Department of Transportation (MDT) will resurface approximately 7 miles of Montana State Highway 1 (MT 1) between I 90 and Anaconda to add safety improvements and provide for routine highway maintenance. The project is expected to begin in late spring or early summer 2022 and take approximately four months to complete. Additional project details are available in this Fact Sheet. Once a firm project start date is set, an informational mailer will be sent to local residents and businesses, and project updates will be posted on this website.

Among planned safety improvements are upgrades to the guardrails at the I 90 interchange and on five bridges along the project route. Pavement resurfacing will include skid-resistant features.

MDT anticipates that at least one lane of MT 1 will be open throughout the project, except for a brief closure at I 90 and MT 1 to upgrade the guardrails. During the brief closure of the I 90 Anaconda Exit 208 interchange, a detour at Gregson/Fairmont Exit 211 will be in place for westbound I 90 traffic to Anaconda, along with a detour at Warm Springs Exit 201 for eastbound I 90 traffic.

To ensure these projects meet all MDT quality and cost criteria, they have progressed through development, surveying, and design phases prior to final construction.

The public and local stakeholders will be kept informed throughout the project. As with all its road construction projects, MDT is committed to and encourages public involvement. Regular updates on construction progress will be posted on MDT's Anaconda-Deer Lodge Road & Bridges Preservation webpage under Project Updates.
