KEY WEST (CBSMiami) – Two New York unicyclists arrived in Key West Sunday afternoon after pedaling 106 miles along the Florida Keys Overseas Highway as a performance art project.

Sculptor Robert Hickman and circus performer Keith Nelson reached Key West’s southernmost point.

Keys officials, including Undersheriff Rick Ramsay, said they’ve never before heard of anyone traversing the Overseas Highway by unicycle.

Brooklyn residents Hickman and Nelson began Tuesday in Key Largo. Pedaling across 42 bridges over the Atlantic Ocean, Florida Bay and Gulf of Mexico, they followed the route of the century-old Florida Keys Over-Sea Railroad that evolved into the contemporary Overseas Highway.

Their Florida Keys Overseas Heritage Trail Unicycle Tour was a highlight of the open-air Sculpture Key West exhibition that continues through March 23.
