The Missouri Department of Transportation will begin work to renovate the ramps at the I-44/I-55 interchange in St. Louis City starting in early 2016. Crews have not determined the specific dates to start work.
Drivers who use the interchange can expect one lane closed on each ramp around the clock, and full ramp closures overnight and on weekends. More details on the schedule will be released when they become available.
For more information on the project, and established detour for ramp closures, please see the project page.
