Jonathan Hulton Bridge

Advantage Steel and Construction performed the erection of 12,100,000 lbs. of structural steel over the Allegheny River. Erection of the multi-girder bridge was performed with land and marine-based crawler cranes. Multiple falsework towers and tie-down systems were installed to stabilize the girders, with haunch girders over 21’ deep and weighing over 150,000 lbs. The main channel span was pre-assembled on sectional barges, which were 60’ x280’ and weighed over 1,050 tons. The barges were then floated into place, and the single unit, weighing over 2 million pounds, was strand-jacked into position to avoid interfering with river traffic.
