Traffic shift begins at Twin Tunnels for westbound tunnel widening project

IDAHO SPRINGS, Colo. - Westbound traffic will now be using the eastbound side of the Twin Tunnels, and the eastbound side will be returned to the detour, while the second phase of the tunnel widening project is done.

The detour road that eastbound traffic will take around the mountain is the same one that side of Interstate 70 used while the eastbound tunnel was widened last year. The project added one lane to that tunnel, for a total of three, and will do the same to the westbound side.

The Colorado Department of Transportation says the widening work is scheduled to be complete by the end of the year.
