Owner:

PennDOT

General Contractor:

Brayman Construction Corporation

Completion Date:

October 2015 

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 was 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.
