Visit New York City and you'll never run out of things to do. In all five boroughs, there is so much to see and experience, but the last thing you might expect in New York is to ride an aerial tram. These things are for the mountains, not a bustling City with millions of people, right? Let me introduce you to the Roosevelt Island Tram. Since 1976, these capsules have glided over the East River connecting Manhattan with the residential neighborhood of Roosevelt Island.

The Park Avenue Tunnel in New York City, also known as the Murray Hill Tunnel, is a historic underground passage originally built in the 1830s to carry the New York and Harlem Railroad. Initially an open cut, it was enclosed in 1850, creating a tunnel that ran under what is now Park Avenue between 33rd and 40th Streets. The tunnel allowed trains to access Grand Central Depot, the predecessor to Grand Central Terminal, but in 1872, passenger train use was stopped south of the depot due to noise and safety concerns. In 1913, following the completion of Grand Central Terminal and the electrification of trains, the tunnel was repurposed for automobile traffic, making it one of the city’s unique thoroughfares for vehicles. Today, the Park Avenue Tunnel is occasionally used for art installations and remains a testament to New York’s evolving transportation infrastructure.
