CDOT culvert replacement project on US 50 north of Montrose to implement traffic shift on Jan. 28

Travel Advisory

Jan. 27, 2026 - Northwestern Colorado - Traffic will be shifted onto eastbound lanes of US 50

Montrose — Traffic utilizing the Frontage Road detour north of Montrose from Mile Point 89.7 to MP 90 will be shifted onto eastbound lanes of US 50 into two-way, single-lane traffic. Traffic shifts will begin at 11 p.m. on Wednesday, Jan. 28, and continue into Thursday morning.

Access to 6300 Road will remain open, and travelers can access the road via the intersection north of the closure. Travelers from the south can access 6300 Road via the intersection north of the Rexel store (refer to map).

The traffic shift will maintain flowing traffic in both directions for the duration of the project.

These culvert replacements will accommodate higher accumulations of rainfall, lower the risks associated with flooding, help maintain the integrity of the roadway and help maintain safe driving conditions. The project is expected to complete in June 2026.
