Overnight closure of US 6 for tunnel repair Oct. 6

October 4, 2019 - Metro Denver Area, Colorado

CLEAR CREEK COUNTY — The Colorado Department of Transportation (CDOT) will close US Highway 6 (US 6) between Colorado Highway 119 (CO 119) and US Highway 40 (US 40) overnight at 9 p.m. Sunday, Oct. 6 until 6 a.m. Monday, Oct. 7. The closure is to conduct necessary tunnel repair work in Tunnel 5 (MP 259.5) as a result of tunnel inspections conducted this summer. The Federal Highway Administration mandates biennial tunnel inspections to ensure safe traveling through the tunnels.


US 6 between CO 119 and US 40 will be closed from 9 p.m. Oct. 6 until 6 a.m. Oct. 7. The closure schedule is weather dependent. Motorists will need to use Interstate 70 both east and westbound as an alternate route around the closure.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.



CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
