Originally intended to be called Murray Bridge, the Big Dam Bridge in Arkansas spans the Arkansas River and Murray Lock and Dam between Little Rock and North Little Rock and is open only to pedestrian and bicycle traffic.

At 4,226 feet (1288 m) in length it is the longest pedestrian/bicycle bridge in North America that has never been used by trains or motor vehicles.

[1] The nickname was given by Pulaski County Judge F.G. “Buddy” Villines, who was concerned about the financing needed and was quoted to say, "We're going to build that dam bridge."

The bridge and adjacent parks are used for several races including the Big Dam Bridge 100 cycling tour, the BDB Twilight 5k race, and the BDB Duathlon.

The Federal Highway Administration gave one of its first Exemplary Human Environment Initiative awards to the bridge, and Illuminating Engineer Society gave its Award of Merit at the international level to the bridge's LED lighting design.
