Lake Ponchartrain Causeway Bridge – USA
The 24-mile behemoth connecting Mandeville, Louisiana to New Orleans is an experience to drive over, to say the least. Not only is the length taxing, but fearful drivers require police escorts at times, and if fog rolls in, drivers must only drive in the right lane and refrain from passing. And when the weather gets especially bad, that’s when the auto incidents begin to stack up. It’s only 16 feet above water, making it the longest above-water highway bridge.
