The 1927 state highway legislation specified a spur route off NJ 4, Route S-4 (later known as NJ S-4A, as several other NJ 4 spurs were proposed), running “from Tuckerton to Little Beach”. While most modern maps do not show a place in New Jersey called Little Beach, many shore denizens know of the island in the Great Bay. It, and several other islands in that area, has been inhabited at times, but was only accessible by boat. However, developers in the 1920s had ideas to turn Little Beach into the next big shore resort, and the State Highway Commission was on board with the proposal, which eventually turned into a series of bridges linking Tuckerton with Brigantine and Atlantic City, with a spur to the south end of Long Beach Island.
The stretch from Tuckerton to the edge of the Great Bay was constructed as Seven Bridges Road (though only five are usable now), and it received the NJ S-4A designation. From the south, a bridge was built over Absecon Inlet between Atlantic City and Brigantine, bypassing an old ferry, and it was also designated as part of NJ S-4A. But the rest of the connections proved too costly, and so they were never constructed. Eventually, the last inhabitants left Little Beach, and it and many of the other islands in the Great and Little Bays are now part of the Edwin B. Forsythe National Wildlife Refuge.
Part of Seven Bridges Road is still intact as Great Bay Boulevard, which was turned back to Ocean County and is now CR 601. The portion of Brigantine Boulevard that was built by the state became NJ 87. Later, NJ 87 in Atlantic City was routed onto Huron Avenue, making it easier for traffic from the mainland to get to the Brigantine bridge; the remainder of Brigantine Boulevard in Atlantic City is now NJ 187. Both highways are now under the jurisdiction of the South Jersey Transportation Authority thanks to the construction of the Brigantine Connector.
