Interstate 55 will be closed from Carondelet to Broadway this weekend to allow for the removal of the Holly Hills Bridge.

Interstate 55 from Carondelet to Broadway will be closed in both directions this weekend as the Missouri Department of Transportation demolishes the Holly Hills Bridge.

The project is part of the Interstate 55 Bridge Replacement Project, which also includes the reconstruction of the Delor Bridge, which got underway last month. The total cost of replacing both bridges is $3 million.

Deanna Venker, an engineer with MoDOT, says like Delor, the Holly Hills Bridge needs to be replaced.

"The structure is about 40 years old," Venker said. "So, it's outlived its life. So we are going to be replacing it with a brand new bridge structure. It's going to have sidewalks on both sides of the bridge, for pedestrians to access it."

Venker says I-55 will reopen no later than Monday at 5 a.m.

MoDOT is also closing three lanes on northbound 270 this weekend between Gravois and I-44. Crews will repair bridges in that area.
