I-25 North Project will permanently close parts of the frontage road near CO 60

Travel Advisory

March 29, 2021 - Northeastern Colorado

WELD COUNTY — On April 1, the frontage road east of I-25 will close permanently south of Colorado Highway 60 to Weld Country Road 46. The frontage road located north of CO 60 to Weld County Road 14 will remain open until the CO 60 bridge over I-25 is demolished. 

After the demolition, the section of the frontage road from CO 60 to WCR 14 will also permanently close. Commuters can take Weld County Road 7 or Weld County Road 13 as alternate routes to CO 60 or to Weld County Road 46. 

The closure is necessary for the I-25 North Express Lanes Project taking place between Berthoud and Johnstown. Eventually, the frontage road will close permanently between Weld County Road 40 to Larimer County Road 14. These closures will not only allow for the expansion of I-25 North, but also a newer, safer north-south arterial called the High Plains Boulevard. The frontage road will remain open in a handful of places between Colorado Highway 66 and Weld County Road 40 and north of Larimer County Road 14.
