I-45 All Lanes Closed Near DeSoto After Early Morning Crash

Reported June 18, 2026

Reported

A crash early Thursday morning brought all northbound lanes of Interstate 45 to a halt near DeSoto, forcing drivers off the freeway and into surrounding surface streets while first responders worked the scene, according to the Texas Department of Transportation (TxDOT).

• Full Northbound Closure: All northbound lanes on I-45 at Wintergreen Road remained blocked, with TxDOT cameras confirming no lanes were open as of initial reports.
• Fulghum Road Detour: Drivers were being redirected off Interstate 45 at the Fulghum Road exit, pushing traffic onto local roads in the DeSoto area.
• Cause Still Unknown: TxDOT had not released details on what caused the crash, and the number of vehicles or people involved was not confirmed in early reports.
• First Responders On Scene: Emergency personnel were still visible at the crash site when TxDOT cameras captured the closure, indicating the situation was actively being managed.

According to TxDOT, the crash was reported around 5 a.m. at the intersection of I-45 and Wintergreen Road, a stretch of the interstate that runs through the southern Dallas County suburb of DeSoto. Camera footage from TxDOT showed all lanes blocked and vehicles being funneled off the freeway at Fulghum Road, the nearest available exit. The agency had not released any information about the number of vehicles involved, the nature of injuries, or what may have triggered the collision, and the story was described as developing at the time of publication by the Houston Chronicle.

A full interstate closure during the morning commute can ripple outward like a dam blocking a river, with overflow traffic backing up through neighborhoods and side streets that aren’t designed to handle freeway volumes. For example, drivers heading northbound toward Dallas from communities south of the city, such as DeSoto, Lancaster, or Hutchins, would have found themselves rerouted through local intersections at a time when school and work traffic is already building. TxDOT urged drivers to expect delays and watch for emergency vehicles still working the scene.

Where This Stretch of I-45 Fits in the Region

Interstate 45 is one of Texas’s most heavily traveled corridors, running from Galveston through Houston and continuing north through the Dallas-Fort Worth metro area. The section near DeSoto sits in southern Dallas County, where the freeway carries a steady mix of long-haul traffic and daily commuters connecting suburban communities to jobs in Dallas. Wintergreen Road is a cross-street in that corridor that also serves Duncanville and Lancaster, meaning a closure at that interchange can affect a broad swath of southern Dallas County residents who depend on I-45 for their daily commute.

Early morning hours between 4 and 6 a.m. tend to see lower overall traffic volumes but can be particularly hazardous because of reduced visibility, driver fatigue, and the higher speeds that come with lighter traffic. A crash during that window often has outsized effects on the morning rush precisely because cleanup and investigation overlap with the time commuter traffic begins to build, turning what might otherwise be a manageable slowdown into a significant delay for thousands of drivers.

What Drivers Should Know About Freeway Crash Closures

When a major freeway closes for an extended period, the Texas Department of Transportation works alongside law enforcement and first responders to manage traffic flow and restore lanes as quickly and safely as possible. TxDOT’s DriveTexas platform and Houston TranStar both provide real-time updates on lane closures and alternate routes across the state, and checking either resource before leaving home during an active incident can save significant time. The National Highway Traffic Safety Administration (NHTSA) consistently notes that secondary crashes, meaning vehicles striking the original crash scene or emergency responders, are a serious danger during active freeway closures, which is why drivers are advised to slow down significantly and move over when they see flashing lights ahead.

• Check Real-Time Traffic Before You Drive: Platforms like TxDOT’s DriveTexas show active closures and detour suggestions, helping drivers choose alternate routes before entering congested zones.
• Move Over for Emergency Responders: Texas law requires drivers to move to an available lane away from stopped emergency vehicles or reduce speed significantly, protecting the crews working the scene.
• Avoid Distracted Driving Near Crash Sites: Slowing to look at an active crash scene, sometimes called “rubbernecking,” increases the chance of a secondary collision and extends delays for everyone on the road.
• Allow Extra Commute Time During Incidents: When a full freeway closure is confirmed during the morning rush, adding 30 minutes or more to a planned route is a reasonable precaution, since detour roads can quickly become congested as well.
