The US Army Corps of Engineers has awarded American Bridge a contract for construction of two new bridges over the Tennessee River just below the lock and dam of Kentucky Lake. The contract is valued at US$88.6M and will be complete in February 2010. The 10-span road bridge is a deck plate girder structure with a total length of 950m. The 18-span single track railway bridge has an overall length of 943m. American Bridge has developed an erection methodology using float in and strand jack lifting techniques for the main channel span of the roadway bridge. The 1,905t railway truss span will be fabricated in American Bridge’s Coraopolis shops and assembled on falsework near the site, then floated into place.
