February 15, 2013 - TRAFFIC ADVISORY - Central Eastern Colorado/CDOT Region 1 - IDAHO SPRINGS – Day and night lane closures will be in place next week in the Twin Tunnels area on Interstate 70 at the east end of Idaho Springs for electrical work and concrete wall construction. Most all of the work is weather permitting.

Preparatory blasting also continues about every three days.  Blast days and times will not be available until the day prior to, or the day of, the blasting operation and will be provided by calling the project hotline at (303) 327-4034 or by checking one of the sources listed below.

Please be aware that beginning at 10 p.m. on Monday, February 18th, weather permitting, the ramp from eastbound I-70 to Hidden Valley (Central City Parkway- Exit 243) will be completely closed for approximately ten to 11 days for roadway reconstruction.

During the closure, crews will lower the grade of the ramp by approximately two feet to tie into the detour route that will be used during the major reconstruction and blasting of the eastbound Twin Tunnel.  Crews will be working 24 hours a day during the closure to expedite the work.

While the ramp is closed, motorists will travel an additional four miles on eastbound I-70 to Beaver Brook, Exit 247. At the Beaver Brook exit, enter westbound I-70 and travel four miles to Hidden Valley.

Adding a third lane to eastbound I-70 from east Idaho Springs to the bottom of Floyd Hill is part of CDOT’s strategy at reducing congestion along one of the state’s busiest corridors which, in turn, will improve gas mileage and air quality.
