The contract for SC Route 9 Bridge over the Catawba River in Lancaster, S.C., requires the placement of 170-ft. bulb-tee beams weighing 200,000 lb. (90 718 kg). The beams are some of the longest ever erected in the state of South Carolina. In order to place the beams, United Infrastructure of Great Falls, S.C., purchased a brand new 250-ton (227-mt.) 298 Series 2 lattice crawler crane, as well as a 298 HSL.
The new westbound bridge is constructed on an aggressive 13-month schedule in the same location as the previous westbound bridge; both directions of traffic are being carried on the adjacent eastbound bridge.
Only half of the 500-ft.(152.4 m)-wide river could be blocked off at one time during construction with barge platforms. The two Link-Belt's efficient footprint allowed for greater river width, and also eased the logistics of barge placement.
