Northbound I-25 between Mulberry Street and Mountain Vista Drive closed overnight on Aug. 28, Southbound I-25 closed overnight on Aug. 29

August 22, 2019 - Northeastern Colorado

FORT COLLINS – Overnight on Aug. 28, the Colorado Department of Transportation and contractor partner, Zak Dirt, will set concrete bridge girders for the new Vine Drive bridge over northbound Interstate 25. From 7 p.m. on Wednesday, Aug. 28, until 7 a.m. on Thursday, Aug. 29, all northbound I-25 traffic will detour off the highway and onto the immediately adjacent I-25 east frontage road. 

A similar closure will occur overnight on Thursday, Aug. 29 when crews set girders over southbound I-25. 

The schedule is weather-dependent and subject to change. Any changes to the closure dates will be posted on the project website and on message boards along I-25. The Vine Drive and I-25 east frontage road intersection, which has been closed since June, will reopen in advance of the I-25 full closures and is part of the suggested detour route. Uniformed traffic control officers will direct traffic as needed during the full closures. A detour map is posted at https://www.codot.gov/projects/vine-drive-bridge-replacement.

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

Vine Drive between the I-25 frontage roads will remain closed through the end of the year. Since demolishing the old bridge in early June, the contractor has constructed the bridge abutments and supports. After the concrete girders are placed by crane next week, the team will form and pour the new concrete bridge deck. The 3.5-mile detour route utilizes N. Timberline Road, Mountain Vista Drive and the I-25 east frontage road. A detour map is available at https://www.codot.gov/projects/vine-drive-bridge-replacement.

Starting at 9 a.m. on 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. A detour map is posted at https://www.codot.gov/projects/vine-drive-bridge-replacement. The schedule is weather-dependent and subject to change.

PROJECT BACKGROUND

The existing structure will be demolished and replaced with a new bridge carrying Vine Drive over I-25. Improvements will also be made to bridge approaches on Vine Drive and the I-25 frontage roads. Project completion is anticipated in early 2020. Originally built in 1966, the existing bridge warrants replacement as part of the Colorado Bridge Enterprise (CBE).
