The old rusty fence that lined Highway 151 in front of Darlington Raceway has been replaced by a black wrought-iron one. The track surface that chewed up tires so badly that legend has it crushed seashells were mixed into the asphalt has been replaced by a slick blacktop. The entrance over the track that haulers used because the tunnels were too small has been replaced by a gaping entrance underneath Turns 3 and 4.
