MoDOT is closing all lanes of I-64/Highway 40 in both directions between Hampton and the Forest Park Avenue/Grand Ave Exit (Exit 38A) starting at 8 p.m. tonight, (Friday) March 29. The lanes will reopen by 3 a.m. on Monday.
There will be blasting tomorrow morning at 7am and 8am. Crews will be relocating several utilities underneath the roadway.
It's all part of a project to replace four bridges over the highway and to construct a new interchange at Tower Grove and Boyle.
MODOT's Drew Gates says. the detour for traffic heading west, you're going to take Forest Park Avenue till you get to Kingshighway, take Kingshighway, left on Kingshighway, and then get back on westbound 64. if you're going east from St. Louis County to downtown, your detour will be to take Hampton down to 44 and then just follow 44 all the way back up to the Poplar Street Bridge.
