I love the shape of New York’s state highway shields. This particular one, dated June 1957, comes from the last generation of cut-out NY shields; made after the embossed shields, and before the rectangular shields with black backgrounds. I no longer own this shield, but I figure I will probably pick one up again eventually.
NY Route 439 formerly extended from the Goethals Bridge across Staten Island via Forest Avenue to the Staten Island Ferry, and continued in Brooklyn a short distance to the Belt Parkway. It was discontinued in 1968, soon after the Verrazano Bridge was constructed, when ferry routes between Staten Island and Brooklyn were terminated and most cross-island traffic flowed to the bridge via the Staten Island Expressway.
