ST. LOUIS – Traffic troubles could be increasing along part of I-55 beginning Monday morning. That’s when MoDOT crews are moving forward with a significant lane shift and ramp closures.

MoDOT shared Monday morning that crews are closing two northbound lanes on I-55 between Weber Road and Virginia Avenue. Then, crews are going to shift the remaining two lanes of 55 north to the southbound side of the highway.

The interstate will be down to two lanes in each direction between Weber and Virginia after the traffic shift.

At the same time, crews are also going to close the entrance ramp from Germania to 55 north, as well as the exit ramp from 55 north to Loughborough Avenue, and the entrance ramp from Loughborough to northbound 55.

We’re told these ramp closures are projected to last through most of this year.

This is all part of a multi-year project to renovate many of the bridges along I-55 between I-44 in St. Louis City and Lindbergh in St. Louis County.

Additional lane shifts and ramp closure are expected as crews complete work along the corridor. There will also be paving once the bridge work is completed. Construction on the entire project is set to be completed by spring of 2025.
