Progress this week

Crews continue debris removal and begin removal of damaged portions of retaining wall outside the proposed shoring area for the eastbound left lane.  Current offhaul of material is approximately 500 Cubic Yards per day from below the eastbound lanes.  A substantial amount of debris has been cleared to expose the Concrete Box Culvert (CBC) outlet to the river.  Further excavation and reconstruction of the CBC will be required adjacent to the eastbound lanes as the drainage structure has been extensively damaged under debris loads.  

Temporary shoring construction will begin on the eastbound lanes once sufficient debris and the damaged wall is removed.

Westbound work at Blue Gulch currently includes removal of the hillside barrier and damaged roadway post tension slab.

Several other agencies are also working on projects in the canyon including the White River National Forest, Black Hills and Xcel energy companies that are repairing assets that were damaged by the material slides and the CDOT IT team that is looking at repairs to fiber in the canyon. The project team is working closely on coordination with these groups.

This permanent repairs project is necessary due to significant damage caused by major materials slides on July 29 and 31 of this summer. The debris did considerable damage to I-70 at Mile Point 123.5, known as Blue Gulch.


Rainy weather may cause additional material flows and I-70 closures in Glenwood Canyon in the coming months. Motorists planning to travel on I-70 in Glenwood Canyon should pay attention to road conditions on cotrip.org and weather forecasts.
