Moments later, a 2013 Volvo semi-truck, also hauling two bulldozers and driven by a 47-year-old man from Las Vegas, Nevada, struck the same bridge while traveling behind the first vehicle.

Both drivers were wearing seatbelts at the time of the collisions.

As a result of the crashes, all lanes of I-15 were closed for approximately four hours. The Porterville Road bridge was also shut down until further notice while the Idaho Transportation Department assesses and repairs the damage.
