If you travel the Dallas North Tollway (DNT) through Addison, your Sunday morning drive is going to require a little extra planning.

All northbound lanes of the Dallas North Tollway at Keller Springs Road will be closed from 5 a.m. to 8 a.m. Sunday, Feb. 22. During that time, drivers will be forced off the Tollway and diverted to Dallas Parkway.

While the closure window is only three hours, this is a heavily traveled stretch of roadway, and even short-term shutdowns can create noticeable congestion, especially when traffic is funneled off the Tollway at once.

The North Texas Tollway Authority (NTTA) lists the cause of the shutdown as road work. While specific details were not outlined in the advisory, this area has seen ongoing infrastructure and roadway activity in and around Keller Springs in recent months. Work near interchange ramps or frontage roads often requires full closures for safety, allowing crews to complete tasks without live traffic moving directly beside them.

Full closures, even short ones, are typically used when crews need to shift traffic patterns, work overhead, or complete tie-ins that cannot safely be done with lanes open.

What drivers should expect during the closure:

Northbound Tollway traffic will not be able to pass through Keller Springs.

All vehicles will be diverted onto Dallas Parkway.

Expect heavier merging and slower movement near the Keller Springs exit.

If you’re heading north toward Plano or Frisco early Sunday — whether for church, sports, or travel — give yourself extra time.

Alternate routes

Depending on your starting point and destination, you may want to consider:

Preston Road as a north-south alternative.

Midway Road for shorter local trips through Addison.

Adjusting your departure time to avoid the 5–8 a.m. window entirely.

Closures like this are typically scheduled early in the morning to minimize weekday commuter impact, but even weekend mornings can see steady traffic in this corridor.

The bottom line for Sunday

Northbound Dallas North Tollway at Keller Springs will be fully closed from 5 a.m. to 8 a.m. Sunday, February 22, in Addison for road work. Traffic will be diverted to Dallas Parkway.

Plan ahead, build in extra time, and expect slower movement through the area.
