road closure

Know before you go! On July 18, culvert work will begin over Prickly Pear Creek, and Hwy 282 detour routes will be in place. Crews will be working between Haab Lane and Wallace Road. The intersections will be open, but travelers will be directed to the interchanges at Montana City and Clancy.

Access to the “Swimming Hole” at the Highway 282 culvert will also be closed beginning July 18 for approximately 2 weeks. Heavy equipment is needed to make repairs to the culvert and will create unsafe swimming conditions.

Project Overview

The Montana Department of Transportation (MDT) and its partner Helena Sand & Gravel Inc. are improving the drainage structure on Highway 282, commonly known as the Montana City Frontage Road, over Prickly Pear Creek approximately 2 miles south of Montana City. Crews will be installing a large box culvert, new pavement, seal and cover (chip seal), roadside barriers, and upgraded signage. This project aims to avoid future road closures by addressing potential issues with culverts.

Construction is anticipated to begin on July 18, 2024, weather and unforeseen factors permitting.

A full road closure and detour will begin July 18 for approximately 2 weeks. This closure is between Haab Lane and Wallace Road. These intersections will remain open to access the detour routes. This website and our email and text message subscribers will be updated as information becomes available.
