A man is in critical condition after crashing into the back of an 18-wheeler on a Southwest Side highway early Friday, according to San Antonio police.

The crash happened just after 3 a.m. on Interstate 35 south near the Poteet Jourdanton Freeway access road. An exact address is unknown at this time.

The man was allegedly speeding just before crashing into the 18-wheeler, police said.

As a result of the crash, the man’s vehicle rolled off the highway. He was extracted from the vehicle and taken to a local hospital.

The main lanes of the highway were reopening as of 5 a.m.; however, the access road near Poteet Jourdanton Freeway and Palo Alto Road remains closed.

Traffic investigators are investigating.
