The I-25 North Express Lanes project will add a third lane on both sides of the Intersection beginning in Berthoud and continuing north through Fort Collins. These road improvements are intended to increase capacity by adding Express Toll Lanes in both directions, replacing four aging bridges and widening four existing bridges.

On September 12, 2019, construction crews broke ground on the Berthoud phase of the project. Roadwork will include adding the express lane heading north and south, an added carpool lot and transet station and will also include a complete reworking of the interchange at CO56 and I-25.

CO 56 Interchange Project

A big part of the project is to rebuild the CO 56 interchange. As currently built, this exist presents several safety concerns. The additional truck traffic from the Love’s development does not help.

The new project will rebuild the interstate to go over the exit, with cars passing under the highway to travel east and west through Town. The construction will also straighten the highway and remove the horizontal curve that currently exists.

The work on the interchange is expected to begin in Spring 2020. With the rebuilding of the interchange, closures on CO 56 will happen. As construction gets closer, detours and specific timeframes will be shared with the public.

Berthoud Transit Station

A new park and ride lot is also included as part of this project. The Berthoud transit center is an approved plan that would allow those traveling regional transit, like the Bustang service, to park in a lot, cross under the Interstate and have median loading for passengers.  

What to Expect

  • While most of the work will be performed outside the roadway, some nighttime lane closures will be required.
  • CDOT will send advance notification of these closures and updates will be posted here as they become available.
  • Construction activities are weather dependent and subject to change.
  • Please watch for construction vehicles entering and exiting mainline I-25 and obey all posted signage in construction zones.
