Patterson Hamburg Turnpike Bridge

The NJ DOT was busy in 2010 reconstructing bridges in need of repair. The galvanizer was approached to galvanize 11 beams that ranged in length from 89 to 93 long. The bridge that was being replaced was called the Patterson Hamberg Turnpike Bridge in Bloomington, NJ. The alternative to galvanizing these long span bridge sections was to have them spliced into smaller sections, which would have added a great deal of cost. After reviewing the drawings with the contractor, the galvanizer was confident that the beams could be progressively dipped.

The galvanized steel will keep the concrete reinforced with no premature cracking.

The end product on the bridge was to be cast in concrete after it was erected. The choice for galvanizing these beams came after many NJ State DOT inspections of steel reinforced concrete bridges. Many non-coated steel reinforced bridges were corroding and deteriorating the concrete. Hot-dip galvanized steel, when used to reinforced concrete, provides added protection and prevents premature cracking and delaminating.

The end result of this progressive dip is a structure that will resist corrosion for generations to come. The galvanized steel will keep the concrete reinforced with no premature cracking. Hot-dip galvanizing continues to be the best choice for todays infrastructure.
