Oldmans Creek Road Bridge Reconstruction
Garden State Precast Project #:# 19-48967
Project Name: BRIDGE 5-B-5 RECON - OLDMANS CREEK RD
Location:: Woolwich Township, NJ
Project start date: September 17, 2019
Project end date: May 2020
Synopsis of Development:
Design, and fabrication of a modified arch bridge in (6) sections. Design and fabrication of matching precast headwalls (2) and wing wall sections (11).
Technical challenges and project constraints:
-
Match existing HEC 3 design cross section
-
Design modified bin wall/deadmen wing wall anchors
-
Design and outsource fabrication of specialty formwork
-
Overhead electrical wires reduced available area for crane set up, section weight was restricted
-
Development of shipping, rigging and handling for odd shaped units.
Fabrication and Testing Activities:
-
Development of Safety protocol for wing wall fabrication with new bin wall/deadmen anchors
-
Development of supports for bin wall/deadmen anchors
-
Test fitting of all sections in yard prior to shipment
-
Change in fabrication due to Covid-19 pandemic.
-
Modeling bin wall/deadmen anchor system for use on projects on a national level.
Fabrication

Production commenced on 3-5-20 and completed on 4-27-20
Crusers Brook Bridge Project
Garden State Precast Project #: 17-42643
Project Name: NJ ROUTE 206 CRUSERS BROOK BRIDGE DP 17102
Location: HILLSBOROUGH TWP NJ
Project start date: NOVEMBER 2018
Project end date: SPRING 2019
Synopsis of Development:
This is a design-build project that Garden State Precast participated in during a four-year period. The project consisted of twenty-four, large, three-sided frames in a dual run configuration. GSP was involved in the design, production and shipment of the units.
Design Challenges and Project Constraints:
This project was designed and deployed over a four-year period. Challenges included project geometry, barrier HL4 ratings, phase construction, special high-strength concrete, shipment to project site, rigging and handling for a 90 degree roll from form to shipment then another 90 degree roll from shipment to installation. All units also required manufacturing on a 30 degree skew.
Fabrication and Testing Activities:
-
Design, purchase of specific formwork, and production of (24) 33’ x 11’-2 frames
-
Validation on NJDOT Class P2 concrete – 6500 psi.
