State highway projects in and around Denton add up to about $5.37 billion in estimated construction costs, according to the October mobility report that city staff attached to the Nov. 6 Friday Staff Report to the City Council.
The report, prepared by the city's Innovative Transportation Solutions consultant, tracks 11 Texas Department of Transportation projects. Several are under construction, while some of the largest have no construction money yet.
Under construction
- I-35/35E/35W merge: The $588.8 million rebuild of the interchange and the freeway from North Texas Boulevard to U.S. 77 is set to finish in January 2030. A TxDOT update dated Oct. 1 says drivers should expect nightly lane closures and one-lane frontage roads in several spots, and that the Loop 288 off-ramp was removed Oct. 3.
- I-35E at Mayhill Road: The $123.5 million interchange rebuild began in January and is scheduled for completion in April 2029. The report notes the contract carries a 120-day delay. Brinker Road, closed since Aug. 24, was slated to reopen Oct. 17.
- I-35 from FM 455 to View Road: Construction started in February on the $128.7 million widening, with completion projected for March 2029. A small traffic switch onto the new southbound frontage road between Lois Road and FM 455 is planned, date not yet set.
Next in line
On I-35 north of Denton, the segment from north of Rector Road to FM 455 is listed as ready to let for construction in November 2026. Two other segments, from U.S. 77 to Milam Road and from Milam Road to Rector Road, carry let dates of November 2028 and August 2027.
