There are six I-495s. Only one of them is the Long Island Expressway in New York. Only one of them is the Capital Beltway in Washington DC too. Three-digit “interstates” are interstate connector routes.

Except the Long Island Expressway is not a beltway around a city. It go from and end point to the city and does not even connect with I-95. Don’t know why the planners let that happen, except some senator in the 60s or 70s was probably needed for a vote.
