In its previous state, the corridor between northern Ocean City, New Jersey, and southern Longport, New Jersey, contained multiple intersections and a parking lot that had been both inadequate and unsafe. This project aimed to remedy these issues through transportation design, focusing on the redesign of two intersections, parking lot rehabilitation, implementation of a new pedestrian crosswalk, and the restriping of the entire corridor. The Longport intersection was remodeled as a six-way roundabout with 11’ lanes, a 30’ center diameter and a 5’ apron width, maximizing the limited space while increasing safety for all users and streamlining traffic flow through the intersection (Figure 1).
The Ocean City intersection was redesigned as a three-way roundabout with 20’ lanes, a 60’ center diameter and a 15’ apron width, with an additional bike lane for better pedestrian and bicyclist safety (Figure 2).
The Longport Dog Beach was modified to feature an expanded and repaired parking lot, as well as a signalized and raised crosswalk for safer pedestrian use. These changes removed the need for motorists to park along the shoulder by the dog beach, especially during peak volume months (Figure 3).
This has ensured increased safety to pedestrians and motorists using the parking lot. Civil 3D, an engineering design program, was used to redesign the intersections, roadway and parking lot in accordance with AASHTO, NJDOT, and ADA standards and specifications. The estimated engineering cost came out to $24,000 while the estimated construction cost came out to $25,000,000.
