If you were wondering what the loud jack-hammering sound was echoing throughout Downtown and Lower Highland in the middle of the night, here’s your answer:

CDOT crews hacked away at the northbound side of the 15th Street bridge over Interstate 25, part of a larger multi-phase project discussed in yesterday’s post. The highway should be open Sunday morning by around 10 AM. Then, the highway will close again Sunday night for Demolition Day 2. The highway will reopen by 5:30 AM Monday morning.
