Jefferson County, MO – Drivers using Interstate 55 in Jefferson County should prepare for a temporary closure this weekend. According to the Missouri Department of Transportation (MoDOT), crews will close the entrance ramp from Route A to northbound I-55 beginning 9 p.m. Friday, November 7, through 6 a.m. Sunday, November 9.
MoDOT officials said the closure is necessary to allow crews to install a new drainage pipe beneath the ramp. The improvement is part of ongoing maintenance work aimed at improving drainage and roadway safety in the area.
During the closure, drivers will be directed to a signed detour. Motorists traveling on Route A should use U.S. 61/67 to access northbound I-55. MoDOT advises travelers to allow extra time for detours and to use caution when driving near work zones.
The department continues to remind drivers to “slow down and move over” when approaching crews or equipment on the road. Real-time updates and additional project details are available at modot.org.
