Project Announcement

Nov. 6, 2026 - Northwestern Colorado - US 50 paving through downtown Delta set for spring 2027

Delta & Montrose Counties - The Colorado Department of Transportation with prime contractor, United Companies, will begin a resurfacing, culvert repair and concrete box culvert installation project in Delta and Montrose counties beginning next week.

Minimal impacts to motorists will occur for the remainder of the 2026 season with work being performed on Americans with Disabilities Act (ADA) ramps and culvert crossing repairs on CO 348. Additional work will take place on US 50 from the intersection of CO 92 through downtown Delta to the intersection with Confluence Drive, the work consists of milling and paving operations scheduled to take place in the spring of 2027.

Crews will begin work on the ADA ramps and culvert crossings on CO 348 just outside of Delta. Construction will take place during daytime hours from dawn to dusk, Monday through Friday.

The project's resurfacing efforts are expected to provide a smoother and safer driving experience for motorists. Studies show that an even roadway surface decreases wear-and-tear on vehicles and allows for better driver control in variable weather conditions. The concrete box culvert replaces an aging bridge structure and will provide better irrigation flow. Additional curb ramp improvements will also offer better pedestrian accessibility for those who walk, roll and stroll through the area.

The project is anticipated to be completed by June of 2027.

Travel Impacts

• Paving operations on US 50 in downtown Delta are scheduled for spring 2027
• A signed local detour will be implemented around the concrete box culvert installation at Mile Point 11.5 on CO 348. Motorists can drive south on 5400 Road to east Easter Road. before connecting back to CO 348 or continuing east on CO 348 to Dahlia Road to south 5600 Road to east CO 348 into Olathe
• The speed limit will be reduced to 40 MPH through the work zone
• Loads wider than 11 feet will be restricted through the work zone
• There will be one-lane alternating traffic throughout the course of the project on both CO 348 and US 50 through Delta
• Temporary sidewalk and pedestrian crosswalk closures will be in place for concrete curb ramp replacements. Please follow all on-site signage to navigate around active construction areas
• While significant delays are not expected, motorists are encouraged to account for up to 10 minutes of extra travel time when driving on CO 348
• Visit COtrip.org for real-time lane closure updates and road conditions on this project and others throughout the state

The graphic shows the two locations related to the Delta to Olathe resurfacing project. The first phase consists of culvert replacement and resurfacing along CO 348 beginning in November 2026, with the second phase consisting of resurfacing along US 50 through downtown Delta beginning in spring 2027.
