Heads up, Bay Area commuters: there's a traffic change on the horizon that's bound to affect those of you traveling on I-55. Starting today, the Missouri Department of Transportation (MoDOT) is shaking things up by shifting southbound I-55 traffic onto a new patch of pavement stretching from just south of Route Z all the way to north of McNutt Street. So, if I-55 is part of your daily drive, you'll want to pay close attention and be ready for the shift in scenery.

The construction on I-55 is part of a larger project to improve the highway. MoDOT is shifting southbound I-55 traffic to the northbound side using a median bypass while crews demolish the old southbound lanes and bridges. Traffic is expected to move onto the new pavement by Monday, August 4, at 7 a.m., depending on weather conditions, according to MoDOT.

Drivers on I-55 southbound between McNutt Street and U.S. Route 67 have already been navigating construction in this area. The current shift continues efforts to rebuild the roadway and replace aging bridges over Herky Horine Road and Joachim Creek.

MoDOT’s work is part of a broader plan to improve travel and safety along I-55. For updated information on the project, detours, and traffic conditions, visit MoDOT’s official website.
