The project on CO 340 will stretch from Grand Avenue (near downtown GJ) to Redlands Parkway (mile points 9.61 to 13,21). Resurfacing improves driving conditions and safety, and as the work gets done, CDOT can more closely evaluate traffic flow in a growing part of Grand Junction.

It’s Not Just Paving—Here’s What They’re Fixing

CDOT estimates the project will continue until at least July 2026. The work includes bridge deck repairs over the Colorado River, new guardrails, updated striping, and ADA curb ramp upgrades at intersections. Everyone will benefit from an upgrade here, drivers, cyclists, and pedestrians alike.

Timeline, Delays, and What Drivers Should Expect

Construction along CO 340 is already underway, with speed reductions in place, and work is already underway over the Colorado River. The bridge work will cause daytime lane closures from mid-to-late summer. Overnight paving operations will take place between 7 p.m. and 7 a.m. Paving could cause delays. Allow an extra ten minutes to travel through the area overnight. Access will remain open, but drivers should expect slower trips during the project.
