as is to Far Rockaway for the Brooklyn Connection
-Metropolitan Ave-Rockaway Pk.
-QBL Local to 71st Ave
- Howard Beach/JFK- 161 Yankee Stadium, via. RBB, Junction Blvd-LGA, Rikers Island, 161st Street. This line would connect with the at Junction Blvd, LGA Airport, any new Rikers Island development once the jail closes, Hunts Point Ave , Intervale Ave , and Yankee Stadium .
