The Texas Department of Transportation (TxDOT) announced that the multi‑year, $136.6 million reconstruction of the I‑35/Mayhill Road interchange and its frontage roads in south Denton is progressing ahead of schedule. According to a TxDOT project fact sheet, the work is already 31% complete and remains on target for a June 2029 completion.
Project scope and timeline
The 40‑month effort covers roughly two miles of I‑35E between Pockrus Page Road and Loop 288. The project includes rebuilding the two bridges at the I‑35E/Mayhill Road interchange, widening the existing four‑lane frontage roads, and installing new signage and detour routes. Construction began in January and will continue through June 2029, with major milestones already reached.
Current construction activities
TxDOT Public Information Officer Tila Grant noted that the two interchange bridges are “nearly complete.” In October, crews will place beams on the southbound bypass bridge and remove existing driveways on the frontage roads. Throughout the project, daily and nighttime lane closures will fluctuate, but most closures are scheduled overnight to minimize disruption for motorists.
Drivers can expect signed detours and advance‑notice message boards to guide traffic safely around work zones. TxDOT will also issue media advisories and traffic alerts to keep the public informed of significant closures and detours.
Impact on local traffic
The interchange reconstruction is designed to “support growing traffic demands” in south Denton, according to Grant. By widening the frontage roads and modernizing the bridges, the project aims to improve traffic flow, reduce congestion, and enhance safety for commuters and local businesses.
One specific impact noted in the staff report is the full closure of Brinker Road until October 17, a temporary inconvenience that will be mitigated by the posted detour information.
Funding and cost details
The project’s funding totals $139 million, sourced from traditional state and federal programs. The initial bid of $123.5 million was 16.2% below the engineer’s estimate, but the final estimated cost has risen to $136.6 million, as reflected in the fact sheet.
Contractor information
Zachary Construction Corporation serves as the general contractor for the interchange rebuild, overseeing the complex coordination of bridge work, road widening, and traffic management.
What residents can expect
TxDOT emphasizes that while lane closures will be a regular part of the construction period, the agency is committed to minimizing inconvenience. Overnight closures, clear signage, and real‑time traffic alerts are intended to keep Denton drivers moving safely and efficiently as the project moves forward.
Community members are encouraged to stay informed through TxDOT’s website and local news outlets for the latest updates on detours and road conditions.
