A tractor trailer driver's mistake led to his truck getting stuck Tuesday morning under a railroad overpass in Lehigh County.

Upper Macungie Township police said 65-year-old Rex Ruyle, of Houston, Texas, was driving east on Schantz Road about 6:45 a.m.

The 13-foot-6-inch-tall truck hit the underside of the Norfolk Southern railroad bridge, which is west of Ruppsville Road and near Sunset Grille.

The overpass has a height restriction of 11 feet 6 inches, but Ruyle said he thought the signs read it was 13 feet 8 inches.

The trailer sustained "severe" damage and had to be towed from the scene, police said. Norfolk Southern was notified to check on the bridge.

Ruyle will be charged with operating a vehicle that exceeds the size allowed on restricted bridges and highways, police said.
