WHITEHALL, Mont. — The Montana Department of Transportation (MDT) is announcing and inviting the public to comment on a proposal that will resurface about 3.5 miles of Interstate 90 (I-90), west of Cardwell. The project begins at the Montana Highway 69 (MT 69) overpass bridges and extends east, ending at the bridges that cross the Boulder River.
Proposed work includes replacing culverts, pulverizing the existing surface, applying a new overlay, and finishing with a seal and cover (chip seal), upgraded pavement markings, signage, and guardrail. Pulverizing is when a specialized machine crushes the existing asphalt and mixes it with the underlying base material.
The purpose of the project is to take a cost-effective approach to extend the service life of the existing roadway.
Construction is tentatively planned for 2028 depending on completion of design and availability of funds. Temporary construction permits will likely be required for this project. No utility relocations will be required. MDT staff will contact affected landowners prior to survey work. Landowners may be contacted again prior to construction regarding temporary permits.
