Hulton Bridge Strand Jacking

After center girders were pre-assembled on Shugart barges and moved into place the night before the lift, four 600-ton capacity strand jacks, each using 36 - 18mm diameter wire strands, were used to slowly lift the segment 70-feet to the final elevation. The river navigation channel was closed for less than 48 hours to allow for the prepping, lifting, and bolting. Although 105 individual girder segments had already been lifted in order to complete the other spans of the bridge, strand jacking the final preassembled span officially marked the completion of the steel erection segment of this project.
