Oklahoma has initiated a $408 million project to replace the aging Roosevelt Bridge over Lake Texoma, which opened in 1945 and connects Bryan and Marshall counties. The original bridge, classified as functionally obsolete, is being kept open during construction, with work starting on the new four-lane structure that includes improved lighting and a pedestrian path. Funded by state resources and a $124 million federal grant, this project represents one of Oklahoma’s largest bridge investments to date, aiming to enhance safety and capacity along US-70, which sees over 11,000 vehicles daily.

More than eight decades after the Roosevelt Bridge first carried traffic across Lake Texoma, Oklahoma has begun work on a massive replacement project that will reshape one of the region’s most important transportation links.

that → carry → links
The Oklahoma Department of Transportation (ODOT) says the more than $408 million project will replace the aging US-70 bridge while keeping the existing structure open throughout construction.
asserted
project → say → construction
Details from ODOT, Equipment World and local broadcaster KXII confirm the project’s record scale, historic origins and planned 2029 completion.

Details → confirm → scale
The US-70 Roosevelt Bridge opened in 1945, connecting Bryan and Marshall counties across Lake Texoma in southeastern Oklahoma.
asserted
Bridge → open → Oklahoma
The original structure stretches roughly 4,900 feet and consists of 87 spans, including a distinctive Warren through-truss central span.
asserted
structure → stretch → span
ODOT records describe that central span as the only surviving example of its type on Oklahoma’s highway system with a polygonal top chord.
asserted
records → describe → chord
Now, 81 years after its opening, the bridge is approaching the end of its useful life.
asserted
bridge → approach → life
An analysis found the structure at risk of becoming structurally deficient and classified it as functionally obsolete, prompting years of planning for a modern replacement.
asserted
analysis → find → replacement
The new project represents one of Oklahoma’s largest bridge investments.
asserted
project → represent → investments
The contract, valued at $408 million, was awarded to a joint venture between Zachry Construction and Traylor Bros.
asserted
contract → value → Construction
The project is supported by state funding and a $124 million federal Bridge Investment Program grant, which ODOT has described as the largest federal transportation grant awarded in Oklahoma for the project.
asserted
ODOT → support → project
The replacement will feature a new four-lane bridge across Lake Texoma, along with improvements to the US-70 approaches.
asserted
replacement → feature → approaches
The design also calls for full shoulders, improved lighting and a pedestrian path, addressing safety and capacity concerns on the existing crossing.
asserted
design → call → crossing
The bridge is particularly important because US-70 serves as a regional connection between southern Oklahoma and northern Texas, supporting daily commuting, freight movement, tourism and other economic activity.
asserted
bridge → serve → commuting
Latest figures show more than 11,000 vehicles use the corridor each day.
asserted
vehicles → show → corridor
Construction is being delivered through a modified progressive design-build approach, a method being used for the first time.
asserted
Construction → deliver → time
The process allows the transportation department and its design-build team to work together during design and construction planning, with the aim of improving the project’s schedule, design and cost efficiency.
asserted
department → allow → efficiency
Crews have been clearing trees and preparing the construction area, while barges have begun drilling into the lakebed to investigate the ground conditions where the new bridge’s piers will be anchored.
asserted
piers → clear → conditions
Lake Texoma reaches depths of about 65 feet near the existing bridge, adding another layer of engineering complexity to the project.
asserted
Texoma → reach → project
The new bridge will be built while traffic continues to use the old one.
asserted
traffic → build → one
That means drivers will not immediately lose the existing US-70 crossing as construction progresses.
asserted
construction → mean → crossing
Once the replacement is finished, the new structure is expected to provide four lanes of modern roadway, improving reliability and safety for motorists travelling between Oklahoma and Texas.
asserted
structure → finish → Oklahoma
Construction is expected to continue for roughly three years, with the new bridge scheduled for completion in fall 2029.
asserted
bridge → expect → fall
The project therefore marks more than the replacement of an aging piece of infrastructure: it represents the transition from a bridge that has served the region since the postwar era to a new crossing designed to carry traffic for decades to come.
asserted
that → mark → decades
