Meramec Greenway: George Winter Park to Unger Park and Emmenegger Park

George Winter Park is closed due to flooding (May 24, 2024)

Exciting News! Beginning in June, crews will begin removing old signs and installing new wayfinding and interpretive signs along the Meramec Greenway between George Winter and Unger Parks. They will also point people to the new walking and biking path on the I-44 bridge.Right now, there are some sections of this greenway that are not clearly marked and can be confusing for greenway visitors. The new signs will make it easier for everyone to navigate this greenway between both parks and destinations along the way.

This work will not require any greenway closures and is expected to be wrapped up in the fall of 2024.

This section of the Meramec Greenway stretches between Unger Park where the river makes a sharp turn south all the way to George Winter Park. There are scenic river views and plenty of recreational green spaces to explore and enjoy along the way. It connects neighborhoods, a light industrial park, parks, a golf course and historic Old Towne Fenton as it meanders through southwest St. Louis County. There is also a new walking and biking connection over the Meramec River that connects to Emmenegger Nature Park in Kirkwood. It connects with this greenway on the Fenton side at the intersection of Yarnell and Rudder Rd.
