A Gathering Place for Tulsa - Land Bridges

Parks and Recreation

Tulsa, Oklahoma

Brief Summary

Crossland Heavy worked on The Gathering Place Land Bridges, which consisted of four two-lane tunnels that are 408 feet long and 89.5 feet wide. Each bridge has 98 precast concrete arches, which weigh 25 tons individually; these were maneuvered and strategically placed via crane. Additionally, 84 42-inch piers were drilled nearly 20 feet beneath each bridge to support the gigantic arches. Every continuous concrete pier cap is 5 feet wide, 9 feet tall, and 330 feet long. Resting in side-by-side pairs, these bridges have a 20-foot clearance to accommodate nearly every mode of transportation. A 16-foot tree-lined median was also installed between the north and southbound lanes of the land bridges, providing Riverside Drive travelers with a scenic commute as they drive to and from their destinations.

The Land Bridges could truly be called the focal point of the Gathering Place project. The only pair of structures like this in the world, the bridges were erected in the hollowed-out earth, extensively waterproofed, and then soundproofed with berms. Backfill up to 25 feet in some areas was placed on top of and around the completed structures and then planted with lush grass and vegetation. This effect causes the bridges to become tunnels effortlessly running through the 100-acre park. Park visitors walk on top of these massive concrete archways, strolling through the gardens as Riverside Drive traffic flows quietly beneath them. The bridges allowed the park to flow seamlessly and peacefully over one of Tulsa’s busiest roadways.
