An investigation is underway after a truck driver died when an 18-wheeler went off a highway overpass in Allen, Texas, and officials are also looking into the road's infrastructure.
The crash happened Tuesday afternoon at the intersection of U.S. 75 and Stacy Road.
Dash camera video from a witness showed the semi-truck plummeting off the U.S. 75 overpass and bursting into flames. Allen police said it appeared the semi-truck collided with another vehicle, which caused it to go off the highway. The driver of the semi-truck died and was later identified as Gustavo Gomez, 71. The United States Postal Service said Gomez was a contractor who transported mail for the agency.
The investigation into his death includes the now 7-year-old retaining wall barrier that engineers admit was not designed to contain a vehicle of that size.
