PLEASE NOTE: The ramp from eastbound I-70 to Hidden Valley (Central City Parkway- Exit 243) remains closed. It tentatively is scheduled to open the evening of Friday, March 1.
Crews are lowering 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 are working 24 hours a day 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.
