[ARCHIVED] Portion of Gutermuth Road to Close July 13-Aug. 21 for Route 364 Interchange Construction

July 6, 2020

St. Charles County, Missouri – The St. Charles County Highway Department will close a portion of Gutermuth Road July 13–Aug. 21, 2020, to allow for continued construction of the new Gutermuth Road interchange with Route 364. The closure will occur between Norgate Court and Old Gutermuth Road.

“The closure of the road is necessary to allow the contractor to safely connect the new interchange ramps to Gutermuth Road,” explains County Engineer Craig Tajkowski. “We understand that this closure will be an inconvenience, but the new interchange will be a tremendous timesaver for residents and motorists in this area of the county.”

Residents will have access to Gutermuth Road on either side of the closure, but no through traffic will be permitted. Eastbound motorists can detour around the restricted area by taking O’Fallon Road to Westwood Drive to Motherhead Road. Westbound motorists can detour around the restricted area by taking Motherhead Road to Westwood Drive to O’Fallon Road. The Highway Department will use changeable message boards to notify residents in advance of the closure and post signs notifying motorists of the detour.

The construction of the new interchange started Feb. 17, 2020, and is managed by the St. Charles County Highway Department with oversight by the Missouri Department of Transportation (MoDOT). The project is a cooperative effort funded by St. Charles County, MoDOT, and the Federal Highway Administration (FHWA) to improve traffic flow along Route 364. Construction includes:

  • Grading and paving along Gutermuth Road and Route 364 for new interchange ramps.
  • Acceleration and deceleration lanes.
  • Roundabouts.
  • Retaining walls, sound wall, lighting and signage.

The cost for the new interchange is $5.5 million and is expected to be open to traffic by the end of 2020. For more information about the project, please call the St. Charles County Highway Department at 636-949-7305 or visit
