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.
Beginning 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 has proved to be very confusing for people walking or riding bikes to navigate. In 2017, we contracted with Alta Planning + Design to address safety concerns. We gathered community feedback 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. Construction to improve the intersection is underway! The changes include new landscaping , navigation signage, and special pavement markings in white and green that will separate people who are walking and biking at both crossings.

In St. Charles County, Centennial Greenway: KATY Trail to Heritage Museum is a 2.7-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 Lake Memorial 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 Lake Memorial Park or take the KATY Trail to explore historic Main Street in St. Charles and Frontier Park. Construction to extend the Centennial Greenway: KATY Trail to Heritage Museum across Highways 364 and 94 via two bridges is complete! Thanks to these new bridges, 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.
Planning and community engagement to explore the feasibility of a connection from Olive and Price Rd. to Warson Park in Olivette is in the early stages. Plans to connect the Centennial Greenway in and around the 39 North Innovation District continues to move forward. (The district includes 600 acres surrounding the Danforth Plant Science Center, BRDG Park, Helix Incubator, Yield Lab and Monsanto/Bayer.) Other greenway segments slated for design and engineering include a connection between Olive Boulevard and Creve Coeur Lake Memorial Park and Olive Boulevard and the Jewish Community Center in Creve Coeur.
