Site work and new construction of a bridge / tunnel in Kingston, Oklahoma. Design plans call for site work for a bridge / tunnel; and for the construction of a bridge / tunnel.

The Oklahoma Department of Transportation recently selected three design-build teams to bid on its US-70 Roosevelt Memorial Bridge project. The US-70 Roosevelt Bridge, located in Bryan and Marshall Counties, is set to be replaced using a $124 million federal grant awarded in 2024 and state funding to ensure it remains a safe and reliable crossing over Lake Texoma. The bridge currently carries 8,500 vehicles per day. The US-70 bridge originally opened in 1945 and serves as a vital link for travel, business, and recreation in Southeastern Oklahoma. The proposed replacement structure will incorporate more resilience so it can better withstand extreme weather events and will also feature wider lanes, improved lighting, and a variety of modern safety features. This method teams designers and builders together throughout the engineering process to promote greater innovation and expedite project completion by incorporating the builder’s preferred practices into the design. As of December 9, 2025, the design-build teams selected have been identified. Each team received a $2 million contract from the Oklahoma Transportation Commission to work on proposals for an overall design, incorporate innovations, and establish construction phases. After reviewing those proposals, Oklahoma DOT will select one of the three teams in the spring of 2026 to deliver final design and construction services for the bridge replacement project. Construction is anticipated to start in the summer of 2026.
