North Texas drivers who use northbound U.S. Highway 75 (Central Expressway) between Northwest Highway (Loop 12) and Interstate 635 should plan for overnight delays this week.

According to TxDOT, the three left lanes of northbound U.S. 75 in that stretch are scheduled to be closed nightly from 8 p.m. to 5 a.m. through Thursday, Feb. 26, 2026.

Even though this is an overnight closure, it’s happening on a corridor that stays busy well past sunset — so it can still affect late-evening commutes, airport runs, and anyone working non-traditional hours.

The work is part of the larger U.S. 75 “Technology Lanes” project managed by TxDOT, which is converting the existing HOV lanes into peak-hour technology lanes from I-635 in Dallas County to SH 121/Sam Rayburn Tollway in Collin County.

The project modernizes how the managed lanes function, shifting away from the older HOV setup with restrictive entry and exit points toward a more flexible system. Construction includes replacing the double white stripes/pylons with broken white striping so drivers can move between the technology lane and general-purpose lanes more continuously, depending on when the lane is restricted or open. All road work is expected to be completed by the end of 2026.

What drivers should expect overnight:

With three left lanes closed, traffic will be pushed into fewer lanes, and that typically creates:

Slower speeds and stop-and-go flow approaching the work zone

Last-minute merging near the closure points

More crashes from lane changes (especially on Central at night)

Also keep in mind: overnight work is always subject to change based on weather or field conditions, so the setup may look different night to night.

Ways to avoid delays:

If northbound U.S. 75 is usually your route during those overnight hours, a few practical options can help:

Use the Dallas North Tollway for longer northbound trips (especially if you’re going toward Plano/Allen/McKinney).

Stay on surface streets parallel to 75, like Greenville Avenue, if you’re moving within central/northeast Dallas and can avoid the freeway merge points.

If you must take 75, build in extra time and merge early, don’t wait until the cones force the merge.
