Jefferson County, MO – Drivers planning to use Route A to access northbound Interstate 55 this Friday night should prepare for an overnight closure, according to the Missouri Department of Transportation (MoDOT).
Weather permitting, crews will close the ramp from Route A to northbound I-55, along with the right lane of northbound I-55, on Friday, January 9, from 9 p.m. to 5 a.m. Saturday, January 10. The closure will allow crews to set bridge girders for the I-55 bridge over Central Avenue.
According to MoDOT, a signed detour will direct drivers around the closure. Motorists can take U.S. Route 61/Route 67 north toward Herculaneum, turn left onto McNutt Street, and use the ramp on the right side of McNutt to re-enter northbound I-55.
The temporary closure is part of ongoing bridge construction work in Jefferson County. MoDOT urges drivers to plan ahead, expect minor travel delays, and watch for crews working in the area overnight.
