Let's see....
Routes coming south onto Main St and terminating can do this instead:
Go south onto College Point Blvd, left onto Roosevelt, terminal somewhere, left onto Prince, left onto 39th Av, right back onto College Point Blvd. Can the Q65 do this? Maybe.
Now the Q17 and Q27 can maybe go right onto Sandford, left onto Union, left onto Roosevelt, terminate, then go back onto Main and Kissena southbound.
Q44 and Q20 back to the Q13/Q16/Q28 loop!
Now all that's on Kissena is... um, the Q25, Q34, and Q65? I dunno.
