Bakke Bro is an old suspension bridge crossing the river Sira, in Vest-Agder county, Norway. It’s one of the most spectacular bridges in the world.
The stone bridge with two arches, also known as Bakke Bru, was completed in 1844. The two towers were built from natural stone. The span between the bridge towers is 53.5 meters and the width is 4.35 meters.
The bridge carries the iconic Tronåsen (Fv946), one of the steepest roads in the world (25-33%). This steep, narrow and winding road was completed in 1844 but was in operation since 1791.
