Sections of Route 364 and Route 94 to Be Closed Overnight Starting Sept. 11

Closures Will Allow for Installation of New Pedestrian Bridges for Centennial Greenway Expansion

Motorists traveling in St. Charles County should be aware of the overnight closures of Routes 364 and Route 94 starting next week so crews can place pedestrian bridges as part of Great Rivers Greenway’s Centennial Greenway project.

On Monday, Sept. 11, crews will place the bridge segment over westbound Route 364. Drivers can expect the following:
-At 7 p.m., crews will close the left lane of westbound Route 364 at Muegge Road to Heritage Crossing.
-At 9 p.m., all lanes of westbound Route 364 will be closed at Arena Parkway to Heritage Crossing.
-All westbound lanes are expected to be open by Sept. 12 at 4 a.m.

On Tuesday, Sept.12, crews will place the bridge segment over eastbound Route 364. Drivers can expect the following:
-At 7 p.m., crews will close the left lane of eastbound Route 364 between eastbound Route 94 and Arena Parkway.
-At 9 p.m., all lanes of eastbound Route 364 will be closed between eastbound Route 94 and Arena Parkway.
-All eastbound lanes are expected to be open by Wednesday, Sept. 13, at 4 a.m.

On Monday, Sept. 18, crews will place the bridge segment over westbound Route 94. Drivers can expect the following:
-At 7 p.m., crews will close the left lane of westbound Route 94 from the eastbound Route 364 Loop Ramp at Muegge Road to Heritage Crossing.
-At 9 p.m., all lanes of westbound Route 94 will be closed from the eastbound Route 364 Loop Ramp at Muegge Road to Heritage Crossing.
-All westbound lanes are expected to be open by Tuesday, Sept. 19, at 4 a.m.

On Tuesday, Sept. 19, crews will place the bridge segment over eastbound Route 94. Drivers can expect the following:
-At 7 p.m., crews will close Exit 13 from eastbound Highway 364/94, preventing access to eastbound Route 94.
-At 9 p.m., all lanes of eastbound Route 94 will be closed from Exit 13 to Portwest Drive. Drivers will not have access to eastbound Route 94 from South St. Peters Parkway as part of the closure.
-All eastbound lanes are expected to be open by Wednesday, Sept. 20, at 4 a.m.

“All project partners are working together to minimize inconvenience to the people who live and work in this area,” said Patrick Owens, Great Rivers Greenway Project Manager. “We appreciate everyone’s patience and cooperation as we bridge these two highways so people will soon be able to safely walk or ride a bike to get where they need to go.”

All work is weather-permitting and could be shifted due to inclement weather. The bridges will be assembled on site and then separately hoisted into place over Routes 364 and 94. Both bridges are part of the project extending the existing 2.2-mile Centennial Greenway in St. Charles County that links the Heritage Museum to the KATY Trail. When complete, the paved greenway will extend an additional mile north across both Routes 364 and 94 and connect to Old Highway 94 near Muegge Road.

Greenway construction is expected to last through the end of the year.
