2012 Top 10 Bridges: No. 8

Feb. 21, 2013
PROJECT: AMELIA EARHART BRIDGE
LOCATION: Atchison, Kan.
COST: $60 million
LENGTH: 2,545 ft
DESIGNERS: HNTB Corp., Mactec, CBB and Kansas DOT
CONTRACTOR: Archer Western Contractors
OWNER: Kansas DOT, MoDOT

Amelia Earhart herself would appreciate how this bridge project took ? ight. The job consists of constructing four units of prestressed concrete girder spans and a 527-ft continuous tied-arch span, and features a unique ?ooring system and deck. HNTB designed each tie girder to bolt together rather than welding them. The move will make the span more redundant. The stringers also have slotted connections on every other ?oor beam. A ternary concrete mix was used on the bridge deck.
