At least two corners at Woodside Avenue and 69th Street, near the entrance/exit of the Brooklyn-Queens Expressway, used to have one or two “arrowhead” directional signs. Almost invariably, arrowheads or triangles pointed the way to bridges, while circle-shaped signs pointed to tunnels.
The Department of Transportation now removes these signs when made aware of their presence, and these disappeared at least a year ago.
