A new infrastructure improvement project, which will replace and repair bridges along Gravois Greenway and Grant’s Trail between Interstate 55 and Officer Blake C. Snyder Memorial Park, has been announced by the St. Louis County Parks and Recreation Department. This project is being done in collaboration with Great Rivers Greenway.

The project will replace two bridges and repair a third, “enhancing safety and long-term use of this popular greenway,” according to the county.

This section of the trail will be closed for approximately 90 days in order to complete these upgrades. The closure is expected to begin on Jan. 5 with the goal of reopening in spring 2026, depending on weather conditions.

“We appreciate the community’s patience as we complete these upgrades to ensure the greenway will remain a safe and enjoyable space for years to come,” said Claire Mueller, Communications Manager at Great Rivers Greenway.

There will be a marked detour along alternate park paths and Green Park Road for trail users for the duration of the closure. For the most up-to-date information and detour map, click here.
