Great Rivers Greenway and Olivette are partnering to build an extension of the Centennial Greenway through Olivette so that people can connect on foot, bicycle, stroller, and wheelchair to the parks, the new Olivette Community Center, and Olive Blvd.

The greenway construction supports actions identified in the Olivette Bike and Walk Plan, the Olivette Parks Master Plan, and the Great Rivers Greenway Regional Plan.

This greenway will include:

    Paved trail for walking, running, bicycling, pushing a stroller, and using a wheelchair

    Native plants to restore the streambank, manage stormwater near the headwaters of the River des Peres, and create a quality habitat for native wildlife

    Amenities such as benches and signs with information about the nature, culture, and history of the area

    Connections to local destinations such as Warson Park, the new Olivette Community Center, Indian Meadows Park, and the Olive Blvd. stores and restaurants

Greenway Goals

The goals of the Centennial Greenway in Olivette are to:

    Connect people and places within Olivette and to the surrounding region

    Create safe and comfortable places for residents of Olivette and the surrounding region to exercise, commute, relax, and connect with nature and other people on the greenway


    2018 – Great Rivers Greenway and the City of Olivette worked with community members to study the area and identify the preferred route for the future greenway

    2019 – Greenway phases were identified for further planning and design

    2020 – Olivette community members provided input to guide the greenway design from Warson Park to Dielman Road

    2020 – Great Rivers Greenway and the City of Olivette met with neighbors who live next to the future greenway to address any concerns in the greenway design such as including new fencing and landscaping

    Summer 2021 – Greenway design will be completed from Warson Park to Dielman Road and along Olive Blvd. near I-170

    Fall 2021 - Greenway construction will begin in Warson Park in coordination with the construction of the Olivette Community Center

    2022-2023 - Greenway construction will continue from Warson Park to Dielman Road and along Olive Blvd. near I-170 in coordination with Olive Crossing

    2023-2025 – Greenway will be designed and built from Dielman Road to Olive Blvd.

Through a separate project to reduce sewer overflows and backups in basements, the St. Louis Metropolitan Sewer District will be replacing undersized sanitary sewers along the River des Peres on the opposite side of the greenway from 2022-2024. More information is available at


The project will be brought to life through several different funding sources. Beyond the local sales tax dollars from Great Rivers Greenway, $1 million in federal funds have been awarded for this greenway construction through the Transportation Alternatives Program. Both Great Rivers Greenway and the City of Olivette save money by working together to coordinate the greenway and community center construction as well as park improvements at the same time. The total greenway construction cost is $4.6 million.


Greenway designers are currently working to understand the potential impact of the greenway construction and provide benefits to the surrounding natural community. The greenway design will work to improve water quality, prevent erosion and stormwater pollution, prevent impacts to migratory birds and threatened and endangered species such as native bats, and integrate cultural heritage.

Several steps will be taken to protect trees and their underground root systems near the greenway during construction. During greenway construction, some trees may be removed if they are dead and at risk of dropping limbs, if the greenway cannot be routed around them, if the ground is too steep, or if there are other trees or structures nearby. Over 50 new native canopy and understory trees will be planted in Warson Park alone, along with native flowers and grasses. These plants will improve air and water quality and provide important food and shelter for native pollinators and wildlife.

This section of the Centennial Greenway traces the River des Peres and includes riparian habitat. “Riparian” means an area along a river or stream. This habitat provides important ecosystem services that benefit us all. The plant roots and soil along the streambank soak up floodwater instead of pushing it downstream. The plants in the riparian habitat filter water pollution and provide food and shelter for diverse native wildlife. During greenway construction along the river, invasive plants that harm other plants around them will be removed and native plants will be planted along the streambanks. These plants will help to keep soil in place, prevent erosion, and protect our wildlife and waterways.
