There's nothing like a 25-mile detour plan to make you realize that the Mullica River Bridge is a critical piece of infrastructure on the Garden State Parkway (GSP). If you're traveling to the Jersey shore (made more popular by the TV show of the same name)—or away from it due to a hurricane—the Mullica River Bridge is the travel crossing located at milepost 49.0 of the GSP. The New Jersey Turnpike Authority's (NJTA) "Widening of the Garden State Parkway from Interchange 30 to Interchange 80" program consists of planning and design for 50 miles of mainline widening of the GSP from Somers Point, Atlantic County to Toms River, Ocean County, N.J. When completed, the widening program will provide a third travel lane and shoulders for both the northbound and southbound directions. The widening at the Mullica River crossing will be accomplished with the construction of a new six-span concrete structure to carry northbound traffic, followed by the rehabilitation of the original 1954 eight-span steel structure to carry southbound traffic. The new bridge is designed to handle a four- lane interim traffic pattern, two lanes in each direction, enabling the off-line rehabilitation of the original bridge. The new structure is 1230 ft long and 56 ft 9 in. wide, providing a final configuration of three 12-ft-wide lanes, a 5-ft-wide inside shoulder, and a 12-ft-wide outside shoulder. The rehabilitated structure is 877 ft 6 in. long, and when finished, will be 61 ft 9 in. wide with three 12-ft-wide lanes, a 10-ft-wide inside shoulder, and a 12-ft-wide outside shoulder. The two tangent parallel bridges are 12 ft apart and the approach embankment is retained by mechanically stabilized profile MULLICA RIVER BRIDGE / CITY OF PORT REPUBLIC – ATLANTIC COUNTY AND TOWNSHIP OF BASS RIVER – BURLINGTON COUNTY, NEW JERSEY BRIDGE DESIGN ENGINEER: Parsons Brinckerhoff Inc., Lawrenceville, N.J.
