Construction Begins on I-70 Between Frisco and Silverthorne

Colorado Department of Transportation has begun work widening I-70 eastbound lanes from Frisco to Silverthorne (Mile Points 202-207). This work requires lane closures at the interchange of I-70, US Highway 6 and Colorado Highway 9 in Silverthorne.


  • Most work will take place at night from as early as 8:00pm to no later than 6:00am. Hours will vary based on location.
  • Daytime work hours will be from 7:00am to 5:30pm, Monday through Friday (minimal impacts after noon on Fridays).

Traffic Impacts

On I-70:

  • Two eastbound I-70 lanes will remain open through the entirety of the project
  • Watch for changing traffic patterns and speeds reduced to 55mph
  • Width restrictions on I-70 will be reduced to 11 feet.

At Exit 205

  • Expect shorter left turn lanes from US 6 and CO 9 (Blue River Parkway) onto eastbound and westbound I-70 on-ramps at exit 205 (Silverthorne). These are expected to be in place 24/7 until July 1
  • Expect alternating one-lane closures in both directions at night
  • The width restriction is 10 feet. Pedestrian facilities will detour around active work areas but will remain open.

About the Project

Work along eastbound I-70 includes widening, repaving and striping, as well as widening the bridges over US 6 and the Blue River. A longer deceleration lane and improved signage will enhance the safety at the exit 205 off-ramp. Deer fencing also will be installed in both the eastbound and westbound directions of I-70 between MP 203 to 205. The scenic overlook east of exit 203 in Frisco will build additional truck parking. The overlook will remain closed during construction, but reopen for the winter shutdown period.

Motorists should anticipate up to 20 minutes of additional travel time throughout the project work zone. Expected end date is September 2023.
