AUSTIN (KXAN) — Northbound I-35 near 51st Street in central Austin reopened around 8:30 a.m. after a deadly crash Wednesday morning.

The Austin Police Department says a pickup crashed into a semi-truck around 2:45 a.m. The pickup was pinned underneath the semi-truck.

Austin-Travis County EMS says the driver of the pickup is in the hospital with critical life-threatening injuries. The passenger of the pickup died at the scene.

The closure was about six hours and stretched into the morning commute, causing big backups on the freeway.

Two semi-trucks also collided just south of this crash as traffic was slowing down. No one was seriously hurt in that incident.
