during an evening rush-hour snowstorm in 1982, air florida flight 90 crashed on take-off from national airport, hitting the easternmost of the three highway bridges known as the 14th street bridge. the oldest span, formerly named the rochambeau, is now named the arland d. williams, jr. memorial bridge, in honor of a passenger of flight 90 who survived the crash, escaped from the sinking aircraft, and perished in the potomac river while saving others from the icy waters. the center span is now called the rochambeau bridge, and the western span, the george mason memorial bridge.
