Vine Drive Bridge Replacement Over I-25 North of Fort Collins

As of June 3, those traveling on Vine Drive over I-25 are being detoured as crews replace the bridge there.

    • Note: See updated detour info in the dropdown below.
    • Access to homes and businesses will be maintained.
  • The schedule is weather dependent and subject to change; check this site frequently for the latest updates.

Starting on or after Monday, Sept. 9, the intersection of Vine Drive and the I-25 west frontage road will be closed through late October for reconstruction. During the closure, crews will raise the bridge approach and intersection several feet.

    • For motorist and crew safety, all traffic will detour around the intersection while extensive earth work and grading activities are underway in the narrow work zone.
    • Access for emergency responders only will be provided through the work zone as an alternative to Vine Drive.
    • Access to all businesses along the west frontage road will be maintained from the south.
    • Intersection and bridge approach work will require lane closures and temporary full closure of the Vine Drive / frontage road intersections.

Approaching the Vine Drive bridge on I-25
Approaching the Vine Drive bridge on I-25

In late May 2019, crews began demolishing and replacing the 53-year-old Vine Drive (aka Larimer County Road 48) bridge over I-25 with a new two-span bridge. This work is part of the statewide Colorado Bridge Enterprise (CBE) program, which finances, repairs and reconstructs/replaces bridges.

Work includes:

  • adding shoulders and sidewalks to Vine Drive over I-25;
  • accommodating tall vehicles traveling on I-25 by providing higher clearance beneath the bridge; and
  • improved bridge transitions on Vine Drive and the frontage roads.


Schedule & Travel Impacts

  • Expect an approximate seven-month closure of Vine Drive between the frontage roads on either side of I-25. 

  • Expect intermittent lane closures and overnight full closures of I-25 for demolition and bridge-placement work.
