Between April 26, 1986 and May 24, 1987, the N ran express via the Bridge to 57th Street during evenings, nights, and weekends. Afterwards, N service began running local via the Broadway Line during evenings, nights, and weekends, but they still operated over the Manhattan Bridge. On May 24, 1987, when the N and R swapped routes in Queens, there were additional changes in Broadway service. B service during evenings and weekends, stopped switching to the local track north of 34th Street to serve the Astoria Line. Instead, it skipped 49th Street and terminated at 57th Street.
