Around six months ago, the photographer Salvador Espinoza began spending a lot of time riding the Q100 bus through Queens, New York. The bus departs from Queens Plaza in Long Island City, winds north through Astoria, and ends at Rikers Island, the jail complex in the East River.

The Q100 is the only form of New York City public transit that reaches the jail, Espinoza says. If inmates have no one to bring them home upon release, they’re handed a MetroCard and directed to the bus.

As a kid growing up in Long Island City, Espinoza remembers seeing newly released inmates getting off the bus at Queens Plaza. Now 35, he still lives within minutes of the Q100 terminal, and as he rode the bus to his day job at a pawn shop in the Bronx, he started taking notice of the people boarding the bus with him. With support from the Queens Council on the Arts, he began a photo series, Q100. Select images will be on display at QNS Collective in Long Island City beginning December 10.
