The Montana Department of Transportation (MDT), in partnership with Riverside Contracting Inc. and Knife River Corporation, have completed construction on US Highway 93 (US 93) between Missoula and Lolo.
Roadwork took place July through November, primarily at night between 6:30 p.m. and 6 a.m. to maintain daytime traffic flow. Periodic daytime work also occurred when materials and certain equipment required warmer temperatures.
Construction activities included milling and paving all four lanes of US 93 between Missoula and Lolo, left-turn lane adjustments near Lolo, guardrail updates, sealing the shared-use path, new pavement markings, the addition of shoulder rumble strips, and a high-friction surface treatment.
