With the replacement of the Route 70 over Manasquan River Bridge, the New Jersey Department of Transportation (NJDOT) planned to create a gateway structure to Monmouth and Ocean Counties in the coastal region of the state. The NJDOT also sought to provide a memorial structure for the 170 local residents who died in the September 11, 2001, terrorist attacks. In September 2004, the bridge was formally dedicated as the "September 11 Memorial Bridge." The $53 million project replaced a structurally deficient and functionally obsolete single-leaf, bascule bridge constructed in 1936 with a pair of moder n, high-level, fixed precast concrete bridges. Each 724-ft-long structure has two, three-span continuous superstructure units (119 ft, 120.25 ft, and 120.25 ft long) comprised of bulb-tee girders at 8-ft center-to- center spacing. The superstructures are supported on two abutments and five architecturally treated in-water piers with pile foundations. To accommodate the needs of marine traffic, the bridge underclearance was increased to 25 ft and the navigation channel was widened from 50 ft to 75 ft. profile ROUTE 70 OVER MANASQUAN RIVER, SEPTEMBER 11 MEMORIAL BRIDGE / OCEAN AND MONMOUTH COUNTIES, NEW JERSEY BRIDGE DESIGN ENGINEER: Arora and Associates P.C., Lawrenceville, N.J.
