A 19-year-old man is dead following a single-vehicle crash early Tuesday morning along Interstate 20.

According to the Texas Highway Patrol, the crash happened around 5:20 a.m. near mile marker 190 in Howard County.

Investigators say a 2006 Honda Civic, driven by Pedro Olvera of Roanoke, was traveling westbound when, for unknown reasons, the vehicle veered into the center median and struck a bridge pillar.
