A section of Atlanta Road in Cobb County was closed for hours after a dump truck struck a bridge and left a man dead early Wednesday morning.

The crash happened shortly before 5 a.m. just north of Bolton Road and the Chattahoochee River, Cobb police confirmed. A railroad bridge crosses the road in that area.

The 2005 Mack 700 dump truck, operated by 44-year-old Jason Maddox of Cartersville, was traveling northbound when its bed, which was fully extended in an upright position, collided with the bridge and caused the truck to overturn onto its driver’s side, police said.

Maddox was ejected and died at the scene, officials said.

Atlanta Road remained closed until around 8:30 a.m. as police investigated.

The crash remains under investigation. Anyone with additional information is asked to contact investigators at 770-499-3987.
