The island is accessible via Route 87, which terminates at the end of the Brigantine Bridge, after crossing the Absecon Inlet.
After crossing the channel, the road's designation changes to County Route 638 (Brigantine Boulevard).
The former Quarters Inlet originally separated Brigantine Island from Peters Beach on the southwest, but through sand deposition Brigantine Island has extended its length and enclosed Peters Beach; Quarters Inlet is now closed.
Two hotels for summer boarders are found here, Holdzkom's and Smith's, and a number of private residences have been erected on its southern part since the popular growth of Atlantic City.
[3]By 1904, Quarters Inlet had taken on an "S" shape, curving in front of Peters Beach and separating it from Brigantine Island.
