U.S.-based Parsons has announced that it has been selected to lead the design of the $409 million Roosevelt Bridge replacement project. The project is over Lake Texoma in Bryan and Marshall Counties, Oklahoma. On the other hand, the state’s department of transport selected the Zachry Construction/Traylor Brothers Construction Joint Venture to deliver the new two‑mile‑long structure. Parsons joins the significant project as its lead designer.

The replacement bridge will span one of the largest reservoirs in the United States. Furthermore, it will be managed by the U.S. Army Corps of Engineers and will be constructed in two phases. The aim of this is to maintain traffic flow throughout the project’s implementation. The new 63-span structure includes substructure elements extending approximately 150 feet below the lake surface. This reflects the technical complexity and engineering precision required for a project of this scale.

Other Projects

Another project that has been advancing since 2025 is NASA’s Wallops Causeway Bridge in Virginia that broke ground on April, 14. The project’s developments shows the relevance of bridges as an integral medium of transport in the U.S. The new bridge is a collaborative effort of the Federal Highway Administration and NASA. The design-build contract will be carried out by Kokosing Construction Company. The Wallops Island causeway bridge is the sole automotive connection between NASA’s mainland operations and its island-based launch range and operations.

Official Word from Parsons as Lead Designer on the Roosevelt Bridge Replacement Project

In their announcement statement, Parsons showed their gratitude to be part of the Roosevelt Bridge replacement project team. “Parsons has a legendary legacy in bridge design, and this project is another example of how our teams continue to deliver the most complex and consequential infrastructure solutions around the world,” said Mark Fialkowski, president of Infrastructure North America for Parsons.

“We’re proud to partner with ODOT and the Zachry/Traylor JV to modernize this critical crossing over Lake Texoma and strengthen a structure that communities rely on every day.” Originally constructed in 1945, the Roosevelt Bridge has been long overdue for a replacement project. Furthermore, it is a vital regional connector for residents, freight and travelers.

Selection of Parsons in the project brings along 80 years of experience in delivering iconic bridges and major transportation infrastructure. Parsons also brings deep technical expertise in long‑span structures, complex foundations, and resilient design. The firm has delivered more than 4,500 crossings across the world.
