I-70 Vail Underpass Detour Paving Underway with Single Lane Closures

  • 15 October 2015

Preliminary paving work began Wednesday, Oct. 7 on the I-70 Vail Underpass project that will add roundabouts on both the North and South Frontage Roads and an underpass between the West Vail and Town Center interchanges. The preliminary work consists of temporary median paving in anticipation of detours beginning spring 2016.

The cross-over paving work will be taking place throughout October between 7 a.m. and 7 p.m. Monday through Friday and will extend into early November. Motorists may utilize the North and South Frontage Roads as alternative routes during the work to avoid delays that may occur on I-70 due to the single lane closures at MM 175, between the Vail Town Center I-70 Exit (Exit 176) and the West Vail I-70 Exit (Exit 173).

The fall work will take advantage of the current good weather to ensure construction stays on schedule. Major construction will begin in April 2016. At that time, the median cross-over detours will be used to carry all lanes of I-70 traffic on either the eastbound or westbound sides while the underpass bridge is built on the opposite side of the highway. The project is funded by the Colorado Department of Transportation and the Town of Vail and is scheduled for completion by December 2017.
