The Oklahoma Transportation Commission approved on April 6, 2026, the joint venture of Zachry Construction and Traylor Bros. Inc. to move forward with the replacement of the U.S. 70 Roosevelt Bridge over Lake Texoma.
The board approved a $408 million contract for the final design and construction phases with the joint venture. The Oklahoma Department of Transportation (ODOT) will continue design development with the selected team in the coming months. Construction is expected to begin later this summer, with completion anticipated in the fall of 2029.
The project will deliver a modern structure designed to improve safety, reliability and long-term connectivity across the region. The bridge in Bryan and Marshall counties, which opened to traffic in 1945, is a critical transportation link connecting southern Oklahoma and northern Texas. It carries 8,500 vehicles per day.
The U.S. 70 Roosevelt Bridge replacement project will include the construction of a new four-lane bridge across Lake Texoma; improvements to roadway approaches along U.S. 70; enhanced safety features, such as full shoulders and lighting; and coordination with local communities and regional partners throughout construction.
"The next step will be for the selected team to deliver final design and construction services for the bridge replacement project," said ODOT Director of Design Justin Hernandez."
The team was determined through a competitive procurement process using a unique "modified progressive design-build" project delivery method, which allows ODOT to contract with multiple design-build teams to collaborate closely with ODOT personnel during design and construction planning. This approach incentivizes design-build teams to streamline delivery and optimize the design, budget and construction timeline. It is the first time this approach has been used in Oklahoma by ODOT.
The commision said the selected team brings extensive experience delivering large-scale bridge and infrastructure projects across the United States, including projects using unique delivery methods. Their portfolio includes projects focused on improving transportation while minimizing impacts on surrounding communities.
