For most of the 19th Century, Stewart Avenue–which is named for a landowner along its route–was Bay Ridge’s main drag. It “once ran straight up the spine of what was then the western edge of the town of New Utrecht….Today, you can more or less make out Stewart Avenue’s old route on the map by drawing a line from 5th Avenue and 85th Street straight to 7th Avenue and 66th Street. 4th Avenue lies in Stewart Avenue’s old roadbed from 5th Avenue and 95th Street south to Shore Road (you can see that on the map at left at the dotted line saying “Bay Ridge.”) Seventh Avenue assumes Stewart Avenue’s route north of 66th Street. Another all-but-vanished ancient route, Kowenhoven Lane, intersected Stewart Avenue at what is today the confluence of the Gowanus Expressway and 67th Street.–Forgotten NY
