I work in that area. I think it is eng. 42. The Amsterdam Ave exit off of the s/b Cross Bronx is the same exit for the Major degan, it is also in the area I see Eng 42 All the time!!! And yes Amsterdam Ave is in Man. but the exit is in the Bronx!!!
E46/L27 is between 3rd Ave and webster cloese to Rescue 3.
