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 3½ miles as crews replace the bridge there.

  • Note: See updated detour info in the dropdown below.
  • Access to homes and businesses will be maintained.
  • The frontage road on the west side of I-25 between Vine Drive and CO 14 (Mulberry Street) will remain open during this initial construction phase, which will last through late summer.
  • The schedule is weather dependent and subject to change; check this site frequently for the latest updates.

Through late July, the intersection of Vine Drive and the east frontage road will be closed for reconstruction. During the seven-week closure, crews will raise the bridge approach and intersection several feet.

Detours:

  • East of I-25:
    • Mulberry Street (CO 14)
    • County Road 3
    • Mountain Vista Drive (CR 50)
    • Alternate route: I-25
  • West of I-25:
    • Mountain Vista Drive (CR 50)
    • Timberline Road
    • Alternate route: West I-25 frontage road

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.
