The damaged Sky Ridge Avenue Bridge above Interstate 25 in Lone Tree.

Interstate 25 in Lone Tree will be experiencing major closures beginning this weekend as construction crews work to make emergency bridge repairs, the Colorado Department of Transportation said.

Northbound I-25 south of Denver will be fully closed for 18 hours from 7 p.m. Saturday to 1 p.m. Sunday. Two inside lanes of southbound I-25 will also be closed during this time.

Significant delays of up to two hours are expected. Officials urge drivers to avoid the area over the weekend.

This is the only daytime closure currently scheduled; however, there will be several overnight closures of I-25 throughout June.

Northbound I-25 will be fully closed and two lanes of southbound I-25 will be closed from Ridgegate Parkway to Lincoln Avenue from 9 p.m. to 5 a.m. beginning the nights of Friday, Sunday, June 12, June 15 and June 24.

During these closures, delays of 20 to 30 minutes are expected, officials said.

The auxiliary lane on northbound I-25 between Ridgegate Parkway and Lincoln Avenue will also be closed 24/7 during the construction project so crews can use the space to stage equipment for bridge repairs.

Signs will be in place to detour northbound and southbound traffic around the closed areas. Park Meadows traffic should exit on Ridgegate Parkway, turn left, continue to Park Meadows Drive, turn right and continue to Park Meadows Mall.

This construction project will replace the damaged section of the Sky Ridge Avenue Bridge above I-25 in Lone Tree. The bridge was damaged after being struck by a commercial truck in February, officials said.

The Colorado Department of Transportation will replace the damaged portion of the bridge, taking down part of the structure and completely replacing it with a new girder and bridge deck.

All work is scheduled to be finished before the Fourth of July holiday weekend.

The construction schedule is weather dependent and subject to change.
