CDOT to Improve Monitoring and Communications at Wolf Creek Pass Tunnel

August 12, 2015 - Southwestern Colorado/CDOT Region 5 - Tunnel closed next Thursday, traffic detoured onto old alignment.

MINERAL COUNTY – The Colorado Department of Transportation will have work underway August 20th to scope the US 160 Wolf Creek Pass tunnel for future fiber optics installation. CDOT has installed cable from Walsenburg to South Fork, excluding the tunnel. Next summer, crews will complete installation through tunnel, greatly improving remote monitoring and traffic operations.

TRAVEL IMPACTS - To enable crews to survey the area, remove manhole covers and other scoping activities, the tunnel will be closed from 8 a.m. to 4 p.m. next Thursday, August 20. Travelers will detour around the tunnel on the old US 160 alignment.

The fiber optic installation project is expected to be underway next summer 2016.

Note:  This fiber optics installation project—to get underway in the summer (details to come)—will receive funding from RAMP, Responsible Acceleration of Maintenance and Partnerships. RAMP is better coordinating project expenditures and available funding. Under the RAMP program, CDOT will fund multi-year and partnership projects based on year of expenditure, rather than saving for the full amount of a project before construction begins.
