Q26: It used to go all the way to Queens Village, way back when Hollis Court Blvd ran through to Jamaica Avenue (i.e. before the Clearview Expressway was built).
Q27: I agree with the idea of a "Springfield Crosstown" but it should be a separate route. My own idea...
- Q27 between Flushing and either QCC or the old Q75 terminal at 230th Street & 69th Avenue;
- Q57 between Rochdale and QCC.
Q77: No, no, no, leave it alone. Maybe, if the were extended along Hillside, then you could combine Q77 and Q76 to form a "Franny Lew Crosstown" (Q78?).
