Reopened! Larimer County Road 16 under I-25

CDOT and the I-25 North Express Lanes Project have completed construction of new roadway under I-25, a new roundabout and an improved southbound I-25 exit ramp at Larimer County Road 16. Frequent heavy rainfall and standing water created many challenges, but through the efforts of the construction team, eastbound and westbound LCR 16 and the southbound I-25 exit ramp at this interchange reopened on schedule on Monday night, July 10. The new interchange improvements offer a safer drive for motorists and better efficiency in traffic movement. A new southbound I-25 on-ramp will also be completed later this fall.

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.
