2014-2017 NJDOT Inspection of Complex and Movable Bridges


 


HAKS is performing inspections of movable and complex bridges throughout New Jersey for consecutive two-year cycles for the New Jersey Department of Transportation (NJDOT). Complex bridges include thru and deck trusses and long viaducts on busy highways in urban environments. Movable bridges include bascule, draw and vertical lift bridges requiring structural, mechanical, electrical, and underwater inspections.

Several of the bridges are historical signature bridges built in the mid-1920s that are essential to travel in New Jersey. For example, the Route 30 Bridge is a major crossing to Atlantic City and the Rainbow Channel, Ship Channel and Elbo bridges (totaling 60 spans) provide crossings from Somerset Point, New Jersey to Ocean City, Maryland.

CADD or Microsoft Visio drawings are being used for priority repair recommendations, drawings showing bridge elevation views with channel bed soundings for structures over waterways, and structure plan views for vertical and horizontal clearances on structures over highways and/or railroads.

Project Highlights 

  • During the inspection of the US 130 over Raccoon Creek Bridge, several stringers in the lift span had perforations in the webs and up to 50% section loss to the bottom flanges. A Priority 1 letter was forwarded to NJDOT along with repair details.
  • During the inspection of the Route 50 over Tuckahoe River Bridge, an end floorbeam in the bascule span was found to have web losses up to 58%. A Priority 1 letter was forwarded to NJDOT along with repair details.
  • During the inspection of the US 130 over Oldmans Creek Bridge, end floorbeams in the lift span were found to have multiple small perforations. Due to their number and proximity to each other, it was determined that buckling was possible and a Priority 1 letter was forwarded to NJDOT along with repair details.
