The Amelia Earhart Memorial Bridge is a four-lane road bridge over the Missouri River between Atchison , Kansas and Buchanan County , Missouri . It leads US Highway 59 across the river.
It is named after Amelia Earhart (1897–1937), who was born in Atchison , the aviation pioneer and women's rights activist who disappeared without a trace while trying to fly around the earth before the last stopover on the tiny Howland Island in the Pacific .
The bridge is 776 m (2546 ft ) long and 22 m wide. It has four lanes and a hard shoulder on both sides and is designed for 12,400 vehicles per day. The Stream Bridge is a 161 m (527 ft) network arch bridge . Its two steel, welded parabolic arches have a box-shaped hollow cross-section and reach a height of 27.4 m (90 ft) above the roadway with an arrow ratio of 1: 5.85. The arches are stiffened by an X-shaped wind brace. The hangers are made in pairs.
The bridge was designed by HNTB. The construction started in 2009 was interrupted twice by floods, so that the bridge could only be opened in 2012.
They replaced the same two-lane predecessor without emergency lanes, one of Sverdrup & Parcel planned and opened in 1939 Gerber beam - truss bridge that was blown up in October, 2013.
