Within large office complexes or clusters of university buildings, glassy skybridges often connect buildings, letting students and workers more easily traverse the campuses. But these high-flying walkways are not unique to modern architecture. In fact, skybridges come from an earlier era, and Untapped Cities takes a look at some of the historic structures still floating above the city's streets today. The Jay Street walkway, shown above, was built in 1907 to help the NYC Hospital House of Relief. Today, it connects the apartment and studio of a fashion designer.
Spanning 15th Street, this skybridge at Chelsea Market dates to 1930. It was built to connect the former Nabisco Factory with the snack-maker's offices across the street. These days, it's used by private companies and not open to the public.
