JEFFERSON COUNTY – Drivers who use northbound Interstate 55 between Route Z and Route M should be aware the interstate will close overnight this 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.
