Memorial Park Land Bridge & Prairie

Memorial Park is a 1,464-acre park – one of the largest urban parks in the United States and Houston’s largest wilderness area. In 1955, the six-lane Memorial Drive was built; it dissected the park into two parts and made it difficult, if not impossible, for pedestrians to traverse the park, made the park less ecologically resilient, and disrupted habitat and migration for dozens of species. Now, 67 years later, the Land Bridge & Prairie project is under construction to reconnect and mend the divided park.

The Land Bridge & Prairie design embodies many of the guiding values set forth by the 2015 Memorial Park Master Plan, created by Nelson Byrd Woltz Landscape Architects and informed by more than 3,000 Houstonians who contributed to its development. The Land Bridge & Prairie is a key component of the Ten-Year Plan that accelerates the development of significant projects within the Master Plan and will open to the public in December 2022.

A New Iconic Destination

The Land Bridge & Prairie project and Memorial Park itself are at the center of the most ethnically diverse metropolitan area in the U.S., with a robust healthcare and research economy and a regional hotspot for ecological biodiversity. Situated in the heart of a major urban park, the Land Bridge & Prairie creates a new public use space within the rich cultural and ecological Gulf Coast context and will offer varied and enjoyable experiences that enhance the urban wilderness character of Memorial Park while providing opportunities for active and passive recreation for all Houstonians. Families, students, tourists, and nature enthusiasts will be able to learn more about the native ecologies, and carefully planned trails will accommodate multiple levels of recreational pursuit, from winding paths for leisurely strolls along the Prairie to hills and scrambles for rigorous interval work by runners and cyclists. New vantage points of the downtown and uptown Houston skylines on top of the Land Bridge will provide an iconic gathering place for sunrise meditation, evening stargazing, and special events.

Ecological Restoration and the Coastal Prairie

The Coastal Prairie is one of the most endangered ecosystems in North America, with less than 1% of its historic range remaining today. The Land Bridge & Prairie project will create over 45 acres of Coastal Prairie in the center of Memorial Park, helping to strengthen the surrounding ecologies and bring Houstonians an immersive opportunity to experience and appreciate this critical native ecology. The Prairie will be home to numerous significant and endangered species of flora and fauna and will provide essential food and shelter for migratory birds and insects. It will provide cumulative benefits for generations. The Land Bridge and Prairie is designed to withstand storms and process stormwater while providing a healthy environment for people and animals. Soils and over 200 native species of trees, shrubs, and deep-rooted Coastal Prairie plants have been selected for resiliency and their ability to slow and store stormwater in carefully calibrated channels and wetlands. This soil-deep rehabilitated ecology will sequester atmospheric carbon, provide cleaner air, and improve animal and insect habitat.

Mending the Divide

The Land Bridge itself creates two dynamic connections over Memorial Drive that reunite the north and south sides of Memorial Park while expanding the existing network of trail systems and providing increased connectivity throughout. Two massive tunnels – measuring 400 and 560 feet long – have been built side by side over the Memorial Drive roadway. In early 2022, Memorial Drive shifted into a new alignment, and traffic now flows through the tunnels. Over half a million cubic yards of soils were harvested and reserved from other park sites, such as the excavation of Hines Lake at the nearby Eastern Glades, and from within the Land Bridge & Prairie project boundary and were used to cover the tunnels and create the mounds of the Land Bridge. When completed, this new parkland will symbolize the triumph of “green” over “gray,” healing the divide created by the construction of Memorial Drive.

Innovation and Resiliency

The engineering and construction of the Land Bridge and Prairie required an extensive coordination effort across disciplines: landscape architects, civil engineers, structural engineers, scientists, fluvial geomorphologists, prairie experts, and biologists. It is the largest land bridge in Texas and, unlike others of its kind in the US, the project includes an important hydrological component. A constructed stream bed integrates stormwater management and water quality treatment, as well as functioning as a “habitat” bridge, connecting both flora and fauna over and under the six lanes of Memorial Drive. The project is not just a physical link like most other land bridges; it’s a nexus where complex and multifaceted systems – both human and natural – have been holistically conceived as part of a greater vision.
