A major accident on eastbound Interstate 635 (LBJ Freeway) at Coit and Hillcrest is snarling traffic in an already highly-congested area.
The crash, involving an 18-wheeler and seven cars, occurred shortly before noon Friday. The big-rig ended up in a median with debris spilled all over the roadway.
Several ambulances were requested at the scene, though the conditions of those involved in the crash are not yet known.
The traffic backup along the eastbound lanes of LBJ stretched for at least a mile.
