Outerbridge Crossing: The Outerbridge Crossing is a cantilever bridge which spans the Arthur Kill.  The "Outerbridge", as it is often known, connects Perth Amboy, New Jersey, with Staten Island, New York.  It carries NY 440 and NJ 440, the two roads connecting at the state border near the bridge's center.  The Outerbridge Crossing is one of three vehicular bridges connecting New Jersey with Staten Island, and like the others, is maintained and operated by the Port Authority of New York and New Jersey.  The others are the Bayonne Bridge (which also carries NJ 440 and NY 440), which connects Staten Island with Bayonne, and the Goethals Bridge, which connects the island with Elizabeth.

New York State Route 440: New York State Route 440 (NY 440) is a state highway located entirely on Staten Island in New York City.  The route acts as a connector between the two segments of New Jersey Route 440, running from the Staten Island community of Richmond Valley to the south to Port Richmond to the north.  NY 440 is connected to the two New Jersey segments by the Outerbridge Crossing to the south and the Bayonne Bridge to the north.  It is one of several signed New York State routes that are not connected to any others in the state, and one of only two NYS routes (NY 426 being the other) that is the middle section of another state's highway bearing the same number.  Much of NY 440 is a limited-access highway.  From the Richmond Parkway (Korean War Veterans Parkway) to Interstate 278 (I-278), it is known as the West Shore Expressway.  North of I-278, it is named the Dr. Martin Luther King Jr.  Expressway (also known as the Willowbrook Expressway).  NY 440 is the southernmost state route in the state of New York.

The parkway is designated New York State Route 909C (NY 909C), an unsigned reference route, which continues northeast along Drumgoole Boulevard for a short distance to its end at an intersection with Richmond Avenue.

The bridge is also one of four connecting New Jersey with Staten Island; the other two roadway bridges are the Goethals Bridge in Elizabeth and Outerbridge Crossing in Perth Amboy, and the rail-only Arthur Kill Vertical Lift Bridge, all of which traverse the Arthur Kill.
