The Oklahoma Transportation Commission approved a design‑build contract on item 43 to replace the Roosevelt Bridge on U.S. 70 at the Bryan–Marshall county line, authorizing a guaranteed maximum price of $392,445,181 and adding a $16 million risk reserve for a total commitment of $408,445,181.
Presenting the proposal, Justin Hernandez said the department selected the Zachry Construction–Traylor Brothers joint venture to provide final design and construction phase services and recommended approval. He told the commission the department expects two lanes to be open to traffic by fall 2028 and a full bridge opening by October 2029.
"The project guaranteed maximum price was $392,445,181, to which we added the risk reserve of $16 million," Hernandez said. The commission discussed the bid evaluation process and heard that pricing accounted for 50% of the selection score after technical scoring was finalized.
ODOT Director Tim Gatz framed the replacement as both a safety necessity and a long‑term investment. "This is absolutely an enormous investment for the Department of Transportation, but it is a generational investment in Oklahoma's future," he said, noting repeated damage and longstanding deficiency concerns at the causeway.
A commissioner moved to approve the contract and Commissioner David Dyson seconded the motion; the commission voted to approve the recommendation.
The department said the construction phase is included in its eight‑year construction work plan with work packages intended to commence in federal fiscal year 2026. The design‑concurrent delivery method means design and construction activities will overlap; the approved owner's representative supplement (covered elsewhere on the agenda) will act as an extension of ODOT staff during final design.
Next steps called for executing the contract with Zachry–Traylor Brothers and beginning final design and early construction activities under the progressive design‑build approach. The commission moved on to subsequent agenda items after the vote.
