Mayor Bill de Blasio calls it the BQX streetcar, a proposed 16-mile above-ground line that would link several neighborhoods of Brooklyn and Queens along the East River. The line would run from Astoria south through Ravenswood and Long Island City in Queens, and through Greenpoint, Williamsburg, the Navy Yard, Vinegar Hill, DUMBO, Downtown Brooklyn, Brooklyn Heights, Cobble Hill, Red Hook, Gowanus and Sunset Park in Brooklyn.
There are many potential obstacles, from funding to community approvals. Construction on the new line, if it is approved, is estimated to begin in 2019 and it would not be operational until 2024.
