New Vine Drive bridge over I-25 now open

November 19, 2019 - Northeastern Colorado

FORT COLLINS –The new Vine Drive bridge over Interstate 25 opened to traffic Monday, several weeks earlier than originally planned. This major milestone also means that both the east and west I-25 frontage roads are open after full reconstruction. 

The new bridge is more than double the width of the old one and adds left-turn lanes at the frontage roads to enhance safety and keep traffic moving. Other project benefits include:

  • New shoulders and sidewalks on Vine Drive over I-25

  • Improved bridge transitions on Vine Drive and the frontage roads

  • Higher clearance underneath the structure for I-25 traffic

“Opening the Vine Drive bridge as soon as possible was a priority for our team. With limited connections over I-25 and several at-grade railroad crossings in the area, we understand the importance of this transportation corridor,” said Chris Boespflug, CDOT Resident Engineer. 

With the new bridge now open, the contractor will utilize daytime lane closures on Vine Drive and the frontage roads to install guardrail, finish seeding, place signs and erect fences. Intermittent I-25 lane closures are also necessary while crews complete finishing work and remove temporary barrier walls. 

Sidewalks on the bridge will remain closed through mid- to late December.


Vine Drive closed in early June for CDOT and contractor partner, Zak Dirt, to replace the old bridge over I-25.

Built in 1966, the original bridge warranted replacement as part of the Colorado Bridge Enterprise (CBE). Formed in 2009, the CBE is funded by 2009 FASTER (Funding Advancement for Surface Transportation and Economic Recovery) legislation. The purpose of the CBE is to finance, repair, reconstruct and replace bridges. 

Although this project is not related to the larger expansion of I-25 happening from Berthoud to Fort Collins, the new bridge at Vine can accommodate future expanded capacity on I-25 as well as provide increased safety with shoulders on Vine, as part of CDOT’s Whole System. Whole Safety initiative.

  • Stay Alert! Expect the unexpected.

  • Watch for workers. Drive with caution.

  • Don't change lanes unnecessarily.

  • Avoid using mobile devices such as phones while driving in work zones.

  • Turn on headlights so that workers and other drivers can see you.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
