Monday and Tuesday, 7 a.m. to 5 p.m., Larimer County Road 16 under I-25 will be reduced to one lane of alternating traffic with flaggers for grading and erosion control.

Starting Thursday at 7 a.m. through Aug. 15 at 5 p.m., a full closure of Weld County Road 46 east of I-25 is planned to allow crews to pour concrete manhole aprons at several locations along WCR 46 to reinforce the manhole structures and create a smoother road surface transition.

  • Westbound WCR 46 traffic will take Colorado Boulevard south to Weld County Road 44, turn west, and continue under I-25 on Colorado Highway 56 to County Road 7, turn north and travel to WCR 46.
  • Eastbound WCR 46 traffic will take CR 7 south to CO 56, turn east and continue under I-25 on WCR 44 to Colorado Boulevard, turn north and travel to WCR 46.

There will be a traffic switch on northbound I-25 on Sunday, Aug. 13, with temporary full closures of the northbound I-25 on-ramps at Colorado Highway 60, and the northbound I-25 off-ramps at Larimer County Road 16. These closures will allow crews to paint new lane striping, relocate barriers and switch traffic onto new lanes as the project progresses.

About the Project

Communities along the I-25 North corridor are expanding rapidly, contributing to major economic growth in northern Colorado. The Colorado Department of Transportation is supporting this growth by delivering the expansion of I-25 North. Improvements are currently underway along I-25 between Berthoud and Fort Collins (with more to come from Mead to Berthoud).

This project brings economic, environmental and quality of life benefits for northern Coloradans by:

  •  Making safety improvements to reduce the number of crashes and fatalities.
  •  Decreasing travel time and increasing trip reliability.
  •  Reducing emissions and improving freight efficiency.
  •  Improve congestion and safety.
  •  Rebuilding aging and obsolete infrastructure.
  •  Improving bicycle, pedestrian and transit connectivity.
