PM Drive Advisory: Dallas North Tollway Bridge Work Runs Through December — Two Lanes Closed Each Way, No Full Closure

The Dallas North Tollway's south end is a construction zone for the rest of the year, and Monday's PM drive runs through it. The North Texas Tollway Authority is repairing and resurfacing multiple bridges on the south end of the DNT from October through December 2026 — the mainlane bridges above Harry Hines Boulevard, Forest Lane and Lovers Lane — and the resurfacing is being done under a two-lane closure in each direction. NTTA's own project page is plain about the trade: because the work is staged that way, "no full closure will be needed" — but "drivers should expect delays during construction."

The bridge work is not the tollway's only active front. NTTA is also improving the southbound main lanes of the DNT from I-635 to I-35E — a new overlay, concrete repairs, drainage improvements and restriping — the same stretch that carries the heaviest share of the evening commute out of downtown and the Medical District. Between the two projects, the southbound DNT is the corridor most likely to run slow between 15:00 and 19:00, and the bridges at Harry Hines, Forest and Lovers are where the lanes narrow.

One honesty note for the drive home: NTTA publishes no night-specific closure times for this week on its project page — the two-lane closures are the project's standing pattern through December, not a schedule with tonight's hours attached, and this desk does not invent hours the authority has not published. What is certain is the pattern: lanes closed in both directions at three bridges, active mainlane work southbound from I-635 to I-35E, and an authority telling drivers to expect delays. Build the time in, or take the parallel routes — and the desk's evening file will carry any incident closures as they are reported.
