Centennial Greenway Master Plan

Master Plan Centennial

Master Plan

The master plan for the Centennial Greenway is a 17-mile corridor that stretches between Forest Park in the City of St. Louis and St. Charles County. The greenway will connect the communities of University City, Olivette, Ladue, Clayton, Creve Coeur, Maryland Heights and St. Peters in St. Charles County. A portion of this greenway follows the same route of the 1904 Olympic marathon held in St. Louis as part of the World’s Fair.


Current Status

Centennial-23Beginning with the easternmost section, Centennial Greenway: Forest Park to Washington University to Vernon, it meanders 1.5-miles (paved) from Skinker and Forsyth Boulevards at Forest Park through the Washington University Campus to Delmar Boulevard (along Melville Avenue) in the Loop Business District and north to Vernon Avenue on Ackert Walk.

Further west, Centennial Greenway: Shaw Park to Olive travels along I-170, linking four different communities; Clayton, Ladue, University City and Olivette. The intersection where the greenway crosses Delmar can be very confusing for trail users to navigate. We are working with ALTA Planning + Design to develop both short-term and long term solutions to improve this intersection and make it easier for people to walk or ride a bike across Delmar.

In St. Charles County, Centennial Greenway: KATY Trail to Heritage Museum is a 2.3-mile segment (paved) that provides a vital link between the KATY Trail and St. Charles Heritage Museum Park to the west. It also connects to St. Louis County’s 4.5-mile paved Creve Coeur Connector trail extending from Creve Coeur Park that features a separated lane on the Page Avenue Extension Bridge for people walking or riding bikes to cross over the Missouri River between St. Louis County and St. Charles County. You can walk, run or ride all the way from Heritage Park to Creve Coeur Park or take the KATY Trail to explore historic Main Street in St. Charles and Frontier Park.

Future Connections

Construction to extend the Centennial Greenway: KATY Trail to Heritage Museum across Highways 364 and 94 via two bridges is almost done! There are still some finishing touches that need to be completed such as signage and landscaping. This work will be wrapped up by spring 2018. These bridges are now open so people can safely walk or ride a bike across these busy highways; connecting schools, neighborhoods, parks, and businesses to each other as well as other area attractions like the KATY trail and Indian Meadows Park. They also connect the existing trail system to Wapelhorst Park in the City of St. Charles and Laurel Park in St. Peters. We are planning a ribbon cutting with our  project partners on April 7, 2018. Stay tuned for more details!

Other greenway segments slated for design and engineering in the next two years include a connection between Olive Boulevard and Creve Coeur Park and Olive Boulevard and the Jewish Community Center in Creve Coeur.
