Lumberton Mayor James Sandifer said the Main Avenue railroad crossing is frequently used by heavy machinery and lowboys. While they use hydraulics to lift their loads when crossing the tracks, uneven rail and asphalt created ongoing problems. “When they go to jack the trailer up, sometimes the way the railroad was, the way the asphalt was, they don’t jack it up enough,” he said. “They hit the concrete, hit the asphalt, bend the rail.”
