Planned I-91 extension

In the 1970s there were plans to extend I-91 across the Long Island Sound from New Haven, Connecticut to Long Island in New York. The extension would continue south to the southern shore of the island perhaps along the route of the current William Floyd Parkway in central Suffolk County. It would also provide easier access to New York City via Long Island Expressway, as well as the Hamptons via Sunrise Highway (NY-27).

Miscellany

The They Might Be Giants song "The End of the Tour," the last track off their John Henry album, references I-91 in the following lines:

Never to part since the day we met out on Interstate 91

I was bent metal you were a flaming wreck when we kissed at the overpass
