While the recently deceased [February 2013] mayor Ed Koch has had the Queensboro Bridge subnamed for him during his lifetime, and there was a push to name the 77th Street Lexington Avenue Line subway stop serving the #6 train for him after his decease, his successor also has a spot named for him.
Exit the #7 train at Mets/Willets Point, walk the boardwalk over the Corona Subway Yards and you will be in a circular plaza surrounded by flags as well as commemorative mosaics from the 1939 and 1964 World’s Fairs. This is David Dinkins Plaza, named after the 106th and first (to date, only) African-American NYC mayor, elected in 1989 and serving one term.
Why here? Dinkins, a big tennis buff, was instrumental in getting the nearby Arthur Ashe Stadium built.
