The Direct Connection project involves the reconstruction of Interstate 295,(I-295), Interstate 76, New Jersey Route 42 and portions of local roadways in the Boroughs of Bellmawr, Mount Ephraim and Gloucester City, Camden County. The New Jersey Department of Transportation (NJDOT) proposes to ease traffic congestion within the project envelope by reconfiguring existing entrance/exit ramps, as well as adding new ramps and lanes to support the new traffic pattern. Among the various structures proposed for this reconstruction, extra investigative effort was given to the “Boat Section”, a below-grade section of I-295 that is proposed to pass underneath some ramps and will be supporting not only typical loads attributed to the substructure, but overhead ramp loads as well.
The actual subsurface investigation program comprised over 700 borings with about 45,000 feet drilled. YU’s primary responsibilities included the coordination and controlled inspection of up to 12 rigs working day and night shifts to accommodate traffic schedules. YU’s field engineers where responsible for supervising drilling activities, classifying soil samples, measuring borehole fluid levels, maintaining logs for various field tests such as the field permeability tests, and providing field quality assurance and quality control (QA/QC) services.
