JEFFERSON COUNTY, MO – Travelers in the Herculaneum area should plan for a full closure of McNutt Street under Interstate 55 this weekend as MoDOT crews begin bridge demolition work. The closure begins 9 p.m. Friday, November 21, and will remain in effect through 5 a.m. Monday, November 24, weather permitting.
According to the Missouri Department of Transportation (MoDOT), crews will demolish the old northbound bridge over McNutt Street after recently shifting I-55 traffic onto a new bridge. All lanes of I-55 will stay open during the work, but McNutt Street will be completely closed beneath the interstate.
Detours are posted for both directions:
– Drivers west of I-55 should take southbound I-55 to the Veterans Blvd exit, travel north on US 61/67, and then west on McNutt Street to reach the northbound I-55 ramp.
– Drivers east of I-55 should take northbound I-55 to the Route Z exit, head west, then rejoin I-55 southbound.
MoDOT urges drivers to allow extra travel time and use alternate routes throughout the weekend. All demolition work is weather-dependent.
