ST. LOUIS • Crews are tearing down the Tower Grove Avenue and Boyle Avenue bridges over Highway 40 (Interstate 64) this weekend.
The Missouri Department of Transportation closed Highway 40 in both directions just east of Kingshighway.
MoDOT and its contractor closed the section of highway between Forest Park Avenue and Kingshighway beginning at 8 p.m. Friday. Several ramps leading to the highway in both directions were also closed.
The highway and ramps are expected to reopen by 3 a.m. Monday.
Westbound traffic will be detoured around the closure using Forest Park Avenue and Kingshighway back to the highway. Eastbound traffic heading toward downtown will be diverted to Interstate 44 using Hampton Avenue.
MoDOT is building a new interchange at Tower Grove and Boyle, and replacing four bridges that span the highway. Washington University and BJC HealthCare are partners on the project.
Bad weather could delay some of the work, MoDOT officials said.
