CDOT to close I-70 in Glenwood Canyon for two hours on Wednesday

GARFIELD & EAGLE COUNTIES – In the early hours of Wednesday, Sept. 23, motorists on Interstate 70 should plan for a closure in Glenwood Canyon for the No Name Tunnel lighting replacement project. Eastbound motorists will be stopped at Exit 116 (Glenwood Springs) and westbound motorists will be stopped at Exit 133 (Dotsero). The closure is anticipated to take place from midnight to 2 a.m.  

CDOT and contract partner Casper Electric will be staging equipment and installing the tunnel lighting control center (TLCC) building for the No Name Tunnel lighting replacement project. The TLCC controls the light output of all the tunnel lighting and will allow the traffic operations center in the Hanging Lake Tunnel to monitor the light levels in the No Name Tunnel.

As part of CDOT’s Whole System – Whole Safety initiative, this project will focus on replacing antiquated lighting controls and fixtures with 676 new LED fixtures. The new lighting system will be tied into the Hanging Lake Tunnel Operations Center so the lighting can be monitored and controlled by personnel in the Hanging Lake Tunnel. The updated lights will use less power while allowing more light for the traveling public to have better visibility during the day and night.    

Additional work will consist of: 

  • Slotted drain installation for storm water management
  • Removal of old lighting system and installation of new lighting system.
  • Programming and integration of the lighting control center.
The $3.5 million multi-year project began April 2020 and has an anticipated completion date of January 2022.

OTHER TRAVEL  IMPACTS 
Motorists can expect a westbound single lane closure Monday starting at 7 a.m. through Thursday at 7 p.m.  Hours of operation are Monday through Thursday from 7 a.m. to 7 p.m.  

Lighting replacements are being performed in coordination with the I-70 Glenwood Canyon surface improvement project and communications will be maintained for the duration of the project.
