 The only change in the route path was following Broadway's conversion to one-way southbound between Columbus Circle and Herald Square in 1957, requiring the northbound 5 to turn at 57th Street onto Eighth Avenue en route to Columbus Circle.In the first decade following MABSTOA's 1962 takeover of all Fifth Avenue Coach and Surface Transit lines, several changes to the M5's route were made.After Washington Square Park was closed to bus traffic on September 2, 1963, its southern terminus (and that of today's M2 and M3) was moved to 8th Street west of University Place, then turning on there to 9th Street towards Fifth Avenue.
