The Colorado Department of Transportation has estimated the repairs to both decks of the highway will cost $5 million. Crews have been making progress but CDOT says there’s approximately a month of more work to complete.

On Tuesday a helicopter was used to bring in netting for rock mitigation on the side of the canyon walls.

The massive boulders caused holes in the highway decks and many of those still have to be repaired.

CDOT says as the repair process continues there will be more closures.
