SAN ANTONIO - A jackknifed big rig is causing a traffic mess Friday afternoon just south of downtown.
The big rig jackknifed on the ramp from U.S. Highway 90 West to Interstate 35.
Officers said the driver of a white pickup truck rear-ended the 18-wheeler, causing the big rig to jackknife.
The driver was taken to a hospital with non-life-threatening injuries.
The pickup leaked oil, and crews are in the process of cleaning up the scene.
Traffic is backed up.
Drivers are asked to avoid the area.
