MoDOT Notice: (EDITED) The right lane of Southbound Route 9 underneath I-635 will be closed at night June 4-5 for bridge demolition. The closure will be from 7 p.m. to 5 a.m. each night. This is all part of a rehabilitation project on I-635 which will close some ramps and detour traffic in the I-635/I-29/Route 9/Route 69 interchange.
