Completed in October 2017, this project:

  • Created an I-70 underpass near I-70 mile point 175, connecting the north and south frontage roads between the Vail Town Center and West Vail interchanges.
  • Will help relieve congestion at the interchanges and prevent vehicles from queuing at the I-70 exits at Vail Town Center and West Vail.
  • Will help reduce repetitive I-70 local traffic by providing a direct connection between the core resort village areas and the West Vail mall area.
  • Will enhance multi-modal transportation opportunities within the Town of Vail.

As of Oct. 13, 2017, the new Sandstone Underpass is open to vehicle, bicycle and pedestrian traffic. The Frontage Roads in Vail have also returned to their normal two-way configuration with a lane of travel in each direction.
