Oklahoma breaks ground on the US-70 Roosevelt Bridge replacement over Lake Texoma.

Oklahoma Department of Transportation officials, U.S. Senator James Lankford, Federal Highway Administrator Sean McMaster and local leaders broke ground on Thursday, 10 September 2026, at Lake Texoma State Park in Kingston on the US-70 Roosevelt Bridge replacement, according to KXII’s same-day report and Lankford’s 11 September press release. Soft FLAG: the ceremony date is 10 September; mid-September outlets recirculated the groundbreaking — this pack is not a new COD.

The mechanism is parallel construction. Officials say the existing bridge will remain open to traffic while crews build the new structure alongside it, so drivers face little to no disruption when major work begins this fall (KXII, quoting ODOT Executive Director and Secretary of Transportation Tim Gatz and others). The replacement is planned with four travel lanes plus a dedicated walking and biking path. The original Roosevelt Bridge opened in the 1940s — Lankford’s release dates it to 1942 under the Roosevelt Administration — and has carried traffic across Lake Texoma for more than eighty years as a two-lane span without shoulders between four-lane approaches, creating bottlenecks. Lankford’s office puts daily traffic at about 12,000 vehicles and describes the bridge as functionally obsolete and at risk of becoming structurally deficient.

Cost and federal share, attributed carefully: Lankford’s release calls the project a $409 million Roosevelt Bridge Project and cites a $123.85 million Federal Bridge Investment Program – Large Bridge Project grant awarded in July 2024 — characterised as Oklahoma’s largest federal transportation grant and one of 19 BIP Large Bridge awards nationwide. Gatz, quoted in the same release, rounds the federal piece to “$124 million” covering “roughly 30 percent” of project cost. Soft FLAG: other outlets (including search-result summaries of ODOT and The Oklahoman) have used approximately $408 million for the same project — the desk prints Lankford’s $409 million and the $123.85 million grant figure from his release, notes the ~$408 million variant, and does not force a single reconciled total. ODOT’s own newsroom URL timed out on fetch this pass; KXII and Lankford are the load-bearing opened sources.

Named actors on the record: Tim Gatz (ODOT / secretary of transportation) said the bridge and causeway are at the end of their life span and that the new bridge will include pedestrian and bike access. Sen. David Bullard (R-Durant), in KXII’s report, said school buses and heavy traffic on a span “not designed for this” volume make the crossing a worry. Sean McMaster of FHWA framed the project as fitting a federal “back to basics, roads and bridges” priority. Marshall County District 3 commissioner Chris Duroy pointed to construction payrolls and local spending. Completion is scheduled for late 2029 in KXII’s account and Fall 2029 in Lankford’s — same season, slightly different wording.

What to watch without mood: ODOT notices when major in-water or approach work begins this fall; any updated total-cost figure that reconciles $408m vs $409m; Fall 2029 open-to-traffic confirmation; traffic-management plans if the old span’s condition forces temporary restrictions before the new bridge opens.
