A rock slide closed the exit off U.S. 24 just west of Manitou Springs Monday, and as of 8 a.m. the Colorado Department of Transportation had no estimate of when the rubble would be cleared.
The slide at about 7 a.m. spilled all the way across the ramp off the eastbound lanes of the highway, CDOT said.
There were no vehicles involved when the rocks came down. U.S. 24 remains open.
This story will be updated as more information becomes available.
