Arkansas' Largest Cycling Tour! The Big Dam Bridge 100 is an annual Little Rock, Arkansas event that celebrates the "Big Dam Bridge" over the Arkansas River. The 4226-foot bridge is the longest bridge built for pedestrian and bicycle traffic in North America, and connects over 15 miles of scenic riverside trails between Little Rock and North Little Rock. The Big Dam Bridge 100 offers several routes ranging between 15 and 100 miles, with some beautiful mountain and river scenery, as well as a few challenging hills on the longer routes. The event provides participants with maps, well-stocked aid stations, great volunteer support, and an event t-shirt, a unique finisher medal, food and drinks. The event finish line ends on the beautiful Arkansas River with a BDB100 block party and live music!
