• Rehabilitation plans review
• Construction method review

We were responsible for the bridge rehabilitation plans and construction method review. This historical bridge was built in 1926 and open to traffic 1927 with many bolts rusted and some main truss members were hit by trucks and severely deformed. The swing bridge has a heavily counterbalanced, 57-ft, 10¾-in. back span rotated about its pivot point in a counterclockwise direction when opening, and the 106-ft, 6-in main span responds in the counterclockwise direction to accommodate the skewed river channel. The rehabilitation project included replacement of 110 tons of corroded structural elements, such as gusset plates for the trusses and angles for the many built-up sections, with 128 tons of new steel. About 14,474 rivets were replaced.
