Understand
From west to east, the Upper West Side is oriented along Riverside Drive, West End Avenue which is called 11th Avenue south of 59th St., Amsterdam Avenue called 10th Avenue south of 59th St., Columbus Avenue 9th Avenue, and Central Park West 8th Avenue. All these avenues change from numbers to names north of 59th Street. The 66-block stretch of Broadway forms the backbone of the Upper West Side and lies diagonally across the avenues; it begins at its juncture with Central Park West at Columbus Circle 59th Street, crosses Columbus Avenue at Lincoln Square 65th Street, crosses Amsterdam Ave. at Verdi Square 72nd Street, and then merges with West End at Straus Square aka Bloomingdale Square, at 107th Street.
