There are four different Broadways in New York (the Manhattan/Bronx one, and one apiece for the three remaining boroughs). Two of them (the Manhattan one, obviously, and the Queens one) intersect with some sort of 57th Street.
As a user, you probably want the Manhattan one unless you specify a borough. But as a developer, it's really hacky-feeling to hardcode "this one should immediately be preferred for no apparent technical reason".
I came across a similar problem once for searches that return identically named cities. It turns out that you get pretty close to DWIM if you rank the results by a combination of population and distance-to-current location (that is, you probably do want the smaller city if it happens to be really close).
