Westbound Interstate 76 under the Dahlia Street bridge in Commerce City and the bridge itself will close this weekend for construction, according to the Colorado Department of Transportation.
From 10 p.m. on Friday to 5 a.m. on Monday, westbound I-76 at exit 9 and Dahlia Street over the interstate will be closed for repair work, according to a CDOT news release.

The repair work to the bridge is necessary because its girders — the metal beams that support its structure — were severely damaged in March when a tractor-trailer towing construction equipment hit its outer edge. Plans to repair the bridge started later that month.
This weekend, the following detours are in effect:
Westbound I-76 traffic will use the exit 9 off-ramp to West U.S. 6/South U.S. 85, continue south to 74th Avenue/Colorado 224, turn west and continue to the westbound I-76 on-ramp.
Northbound Dahlia Street traffic will detour east on 74th Avenue/Colorado 224, turn north on U.S. 6/U.S. 85 to join eastbound I-76, exit at 88th Avenue and go west.
Southbound Dahlia Street traffic will detour west on the I-76 Frontage Road, turn east on 74th Avenue/Colorado 224 and continue to Dahlia Street.
Once this weekend’s work is completed, there will be ongoing single-lane closures overnight on I-76, CDOT officials said. The lane will be closed from 7 p.m. to 5 a.m. during the week, and from 8 p.m. to 7 a.m. on the weekend. Northbound Dahlia Street over I-76 will continue to be closed until the project is completed.
CDOT officials expect construction to wrap up in mid-July.
