Only Two Truck Routes in Sunset Park - 39th and 65th

Bet you didn't know there were only two side streets that trucks are supposed to take if they don't have a local delivery.  Here on 44th Street, it sure seems like we've got one of the truck routes based on the number of trucks that go barreling up the hill.  (I know, how do they barrel UP the hill?  But they do!)

Don't believe me about the 39th and 65th Street (and a little of 60th Street) deal?  Here, look: 

The blue lines are LOCAL truck routes, and the red are THROUGH truck routes.
