This project will:

  • Add an I-70 underpass near I-70 mile point 175, connecting the north and south frontage roads between the Main Vail and West Vail interchanges. (The project does not add additional I-70 exits/interchanges into the Town of Vail.)
  • Help relieve congestion at the interchanges and prevent vehicles from queuing at the I-70 exits at Main and West Vail.
  • Help reduce repetitive I-70 local traffic by providing a direct connection between the core resort village areas and the West Vail mall area.
  • Enhance multi-modal transportation options within the Town of Vail.
Phase 4 Map

On Friday, Nov. 18, the north and south frontage roads returned to their normal, two-way alignment—with a lane of travel in both the eastbound and westbound directions.

Gore Creek Trail
Also beginning Nov. 18, access to the Gore Creek Trail on the east end of the project site (adjacent to the Glen Lyon offices) opened to pedestrians and bicyclists. Pedestrian sidewalks along the south frontage road will be installed during phase 4 of the project; pedestrians are advised to use the Gore Creek Trail until then. Along the north frontage road, the North Recreation Path is open in its new at-grade alignment, adjacent to the north frontage road.

The area beneath the underpass will remain closed to vehicles and pedestrians throughout the winter and phase 4 of construction, and will open when the project is complete at the end of November 2017.

Motorists should be aware that when the north and south frontage roads reopen to two-way traffic, the area is still an active construction zone with reduced speed limits.

Plan your drive using this project webcam. Select "Control" and then "Positions" to view construction from different angles.

Construction contractors are returning to Vail to resume work on the fourth and final phase of the the project. Throughout March, crews will conduct stonework beneath the underpass, requiring minor delays along the north and south frontage roads to direct site access.
