I took driver's ed in high school. The first day driving our teacher always took the students across the Mississippi River on the Huey P. Long Bridge. From Wikipedia:
The widest clean span is 790 feet (240 m) long and sits 135 feet (41 m) above the water. There are three navigation channels below the bridge, the widest being 750 feet (230 m). The distinctive rail structure is 22,996 feet (7,009 m) long and extends as a rail viaduct well into the city. It has sometimes been described as the longest rail bridge in the US, but the nearby Norfolk Southern Lake Pontchartrain Bridge, at 5.8 miles (9.3 km), is considerably longer. The highway structure is 8,076 feet (2,462 m) long with extremely steep grades on both sides. Each roadway deck is a precarious 18 feet (5.5 m) wide, with two nine-foot lanes, but because of the railroad component, is unusually flat for a bridge of this height. Normally, bridges this high have a hump to accommodate the height but this bridge is flat to accommodate rail traffic.
He figured that if you could drive the HPL, you could overcome almost any fear in driving. He was right. Particularly because almost at the top, closer to the Westbank side, there is an unexpected jog of about 2 feet that will catch you unawares. The speed limit is 40 mph.
