Mercer County Bridge 672.4 over Doctor’s Creek

The project required the cofferdam and piles to be installed using low clearance pile driving equipment. The installation of the precast concrete beams required the use of 2 cranes performing a tandem lift. The project was stopped due to issues with the New Jersey Transportation Trust Fund, but after resuming work Simpson & Brown completed the job in the winter months.
