MoDOT to close NB I-55 in Jefferson County at Route Z overnight next week…

JEFFERSON COUNTY - Drivers who use northbound Interstate 55 between Route Z and Route M should be aware the interstate will close overnight next week for bridge construction.

Weather permitting, crews will close all lanes of northbound I-55 nightly from Tuesday, December 9 through Saturday, December 13 between 11 p.m. and 4 a.m. to set girders for a new bridge over the BNSF railroad.

A signed detour will direct traffic around the closure. Drivers will exit I-55 at Route Z (Exit 180) and turn right. They'll then turn left at U.S. Route 61/67 and continue along that route until they reach Route M, where they will turn left, and then take the ramp on the right side of Route M to re-enter northbound I-55.

For additional information about current and upcoming detours and project status, please visit the I-55 Corridor Improvement project website at: Interstate 55 Corridor Upgrades in Jefferson | Missouri Department of Transportation (modot.org).
