I-70 Twin Tunnels Weekly Traffic Advisory

April 25, 2013 - Central Eastern Colorado/CDOT Region 1 - IDAHO SPRINGS – Traffic continues to move smoothly on the two-lane, eastbound Interstate 70 frontage road around the Twin Tunnels.

The daily blasting schedule is posted daily on the project hotline, (303) 327-4034 or webpage –www.coloradodot.info/projects/i70twintunnels
