Between the 1990s and September 2013, the short-turn B15 Spring Creek terminus was a separate branch, directly serving the Brooklyn General Mail Facility via a turnaround loop at the north end of the facility south of Linden Boulevard. The JFK and Postal Facility branches were combined during midday and overnight hours. The loop is still served by terminating and buses, and through service to Wyckoff Heights Medical Center in Bushwick or the Gateway Center in the southern portion of Spring Creek.
