A violent collision between a semi-truck and another vehicle on Interstate 35E in Dallas County left two people fighting for their lives and the highway shut down for more than three hours early Tuesday.
The Crash

The Dallas County Sheriff’s Office first received reports of the wreck at 2:15 a.m. on southbound I-35E just south of Valley View Lane. Deputies arrived to find an 18-wheeler and a second vehicle had collided, causing significant damage to both.
Emergency crews worked quickly to free the injured. Two victims were rushed to a nearby hospital in critical condition, according to sheriff’s officials.
Road Closure
With debris scattered across the roadway and investigators collecting evidence, authorities closed all southbound lanes. Drivers were forced to exit onto Loop 12, creating backups that stretched for miles during the predawn hours.
By 5:30 a.m., crews had cleared the wreckage and reopened the interstate. The cause of the crash remains under investigation.
