The Verrazano-Narrows Bridge (usually called simply “the Verrazano”) opened in 1964 and connects Staten Island with Brooklyn. The bridge has been called the “Guinea Gangplank” (also “Guinea Gang Plank,” “Guintified Gangplank,” and “Ginny”) because of Staten Island’s many Italian residents, especially those coming from Brooklyn. “Guinea” is an ethnic slur for an Italian, and, in recent years, some have referred to Staten Island as “Staten Italy.”
   
     
Wikipedia: Verrazano-Narrows Bridge
The Verrazano-Narrows Bridge is a double-decked suspension bridge that connects the boroughs of Staten Island and Brooklyn in New York City at the Narrows, the reach connecting the relatively protected upper bay with the larger lower bay.
 
The bridge is named for Italian explorer Giovanni da Verrazzano, the first known European navigator to enter New York Harbor and the Hudson River, while crossing The Narrows. It has a center span of 4,260 feet (1,298 m) and was the largest suspension bridge in the world from the time of its completion in 1964 until 1981. It now has the seventh longest center span in the world but still is the largest suspension bridge in the United States. Its massive towers can be seen throughout a good part of the New York metropolitan area, including from spots in all five boroughs of New York City.
 
The bridge furnishes a critical link in the local and regional highway system. It is widely known today as the starting point of the New York City Marathon. The bridge marks the gateway to New York Harbor; all cruise ships and most container ships arriving at the Port of New York and New Jersey must pass underneath the bridge. Most ships, when built, must be built to accommodate the clearance under the bridge. Among local residents it is often referred to as simply the “Verrazano.”

There’s some irony in the idea that many of the new settlers were fleeing what they perceived as “them” (black citizens) by crossing what many Staten Islanders referred to as the “Guinea Gangplank”...

I know your prestigious blood line probably left good ‘ol Brooklyn for that the trip over The Guinea Gangplank to the world’s most toxic garbage dump, the joke of New York…no wait….even worse, they were part of the mass exodus of cheap-ass guineas that didn’t even benefit from the Verrazano Bridge, they boated over in the forties and fifties, thinking they were gonna get something
for nothing in Staten Island. The Big Dream.

Well I could’ve spelled it the “Guinea” Gangplank, but that is and has historically been the official unofficial name for the Verrazano Bridge since before the days that Columbus sailed down Route 22.

This way you just stay on I-278 East through Staten Island, go over the Verazzano Bridge (aka “Gintified Gangplank” by local lingo), left lanes coming off either the top or bottom lanes of the bridge go directly onto the Belt Parkway, and follow that East to LI.

Many times I’ve done the trip especially since it’s shorter and yes that $9 cash or $8 EZ Pass one way Westbound toll on the Verrazzano Gangplank is a big incentive to avoid.

It’s an old Brooklyn joke from all the migratory guineas who fled and bought houses in Staten Island. That’s when the Verrazano bridge got it’s nickname (The Guinea Gang Plank) in the late 80’s and the diehards who stayed in Brooklyn goofed that they moved all the way out there just to live next to the Freshkill dump. That’s where the Twin Towers debris sits and it’s one of the things that the astronauts can spot from space in the Space Shuttle.

If you want me to consider avoiding crossing lower Manhattan on the westbound return, take the ridiculous tolls off the Verrazano Bridge. That would take a lot of traffic out of Manhattan. Notice I said take the tolls off, not change the toll structure. Even then the westbound Guinea Gangplank and SI expressway would just get more clogged pissing off the local NIMBY’s in SI, but it would take very much traffic out of Manhattan.

STIsland is there. The Guintified Gangplank toll needs to be done away with in order to clear much crosstown traffic out of Manhattan.
