Our original story continues below.

Danger from loose rocks led the Colorado Department of Transportation to close a section of Interstate 70 near Idaho Springs on Thursday afternoon.

CDOT also had closed part of U.S. 40, which parallels I-70, but reopened that shortly after 4 p.m.

An agency spokeswoman didn’t know when I-70 would reopen. 

The latest information is available at COtrip, the state’s real-time travel website. Google Maps showed traffic backing up for miles around the closure as of Thursday at 4 p.m.

CDOT closed the roads after blasting work that’s part of the massive expansion of I-70 at Floyd Hill, a steep climb near Idaho Springs that’s notorious for traffic backups. 

Work crews noticed a rock slab coming loose over the highway and made the call to close the roads, “just in case any chunks of rock were to fall,” said CDOT’s Presley Fowler.
