Northbound I-55 to close overnight Saturday in Jefferson County between McNutt and Route Z

JEFFERSON COUNTY- Drivers who use northbound Interstate 55 between McNutt Street and Route Z should be aware the interstate will close overnight this Saturday to shift northbound I-55 onto the median pavement.

Weather permitting, crews will close all lanes of northbound I-55 on Saturday, April 11 from 10 p.m. to Sunday, April 12.

A signed detour will direct traffic around the closure. Drivers will exit I-55 at McNutt Street (Exit 178) and turn right and travel eastbound on McNutt Street to U.S. Route 61/67. They'll then turn left at U.S. Route 61/67 and continue along that route until they reach Route Z, where they will turn left, and then travel westbound on Route Z and turn right before the I-55 bridge over Route Z 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).
