Summary
A presenter summarized progress on the I-70 West Vail Pass auxiliary lane project, reporting a third eastbound lane and a new eastbound bridge opened in fall 2025, resurfacing and a relocated recreation path were completed, and six wildlife underpasses plus avalanche and rockfall mitigation are scheduled for completion this summer.
A presenter summarized progress on the I-70 West Vail Pass auxiliary lane project, saying crews opened a third eastbound lane near Vail Pass in fall 2025 and a new eastbound bridge this fall to improve safety and operations along the I-70 Mountain Corridor.
The update said the work "aims to improve safety and operations in both directions over Vail Pass." Project crews worked around the clock in all weather conditions to keep the schedule on track, the presenter said.
Officials highlighted several specific completions: the third eastbound lane opened in fall 2025; a new eastbound I-70 bridge opened this fall, joining a westbound bridge that opened in 2023; the Vail Pass recreation path was relocated to accommodate roadway improvements; and the highway was resurfaced between Vail Pass and East Vail to provide a smoother driving surface.
The presenter said a new Vail Pass closure early warning system has been installed so drivers can adjust travel plans sooner if the pass closes. Looking ahead, the update said the project will finish six wildlife underpasses and install new avalanche and rockfall mitigation measures this summer. The presenter said project operations will pause for the winter and resume in spring 2026.
For more information or to receive alerts, the presenter directed listeners to text "Vail Pass" to 21000 or visit codot.gov/projects/i70westvailauxiliarylanes.
