Jarrod,
That usually happens when 95/36 go north to Marble Hill or Riverdale, where they are 2d, 3d, (or 4th due on a 10-75) at many boxes.
The 207th Street Bridge is east of 95/36; they cross it on the first alarm only if one or more of E's 43,75, 81, 48, (and maybe 79 and 42) and the corresponding ladder companies are unavailable for a run in the Fordham Hill, Kingsbridge, or Morris Heights sections of the Bronx.
By the way,"Kingsbridge" refers to your King, from the days prior to the American Revolution, when there actually was a bridge authorized by the British Crown used to travel to parts north, outside of New York City.
