The S79 was originally the R103, which ran between St. George Ferry Terminal Ramp "E" and Tottenville. In 1975, it was renumbered the S103. In September 1980, every other S103 bus was rerouted along Richmond Avenue to terminate at the Staten Island Mall, providing service from Staten Island's South Shore. At the same time, every other S102 bus was rerouted to the Mall, providing North Shore service. On January 4, 1987, as part of reductions in bus service on seven routes across the city, S103 service was decreased. While fewer short-run trips to Hylan Boulevard in Eltingville would operate, more frequent service would be operated on the branch to the Staten Island Mall. On April 15, 1990, the S103 was split into two routes; the S78 assumed the Tottenville service, while the S79 assumed the Staten Island Mall service. On June 26, 1992, the
Metropolitan Transportation Authority (MTA) Board voted to approve a service change to reroute the northern terminal of the route from Saint George Ferry Terminal to 86th Street and Fourth Avenue in Bay Ridge, Brooklyn effective in September. The route would be revised to run via Steuben Street, Narrows Road North, and the Verrazzano–Narrows Bridge. Simultaneously, the B8 would be extended to 92nd Street to allow S79 riders to get to the Brooklyn Veterans Administration Hospital with a transfer. The proposed change was opposed by some store owners in Brooklyn and Brooklyn Borough President
Howard Golden, who believed the route would lead Brooklyn shoppers to shop at the Staten Island Mall instead of at Bay Ridge stores. The change took effect on September 13, 1992 as part of the
New York City Transit Authority's Fare Deal improvements program. In April 2001, the MTA announced it would increase the span of S79 service on Sundays from 8:38 p.m. to 11 p.m. from Bay Ridge, and from 7:23 p.m. to 9:50 p.m. from Staten Island Mall due to demand for increased service. The additional service was expected to cost $40,000 a year, and would take effect in July 2001. In July 2001, it was announced that the span of morning service would be extended by two hours on weekends, to take effect in September 2001. The change was expected to cost $50,000 a year. S79 eastbound service previously began at 6:45 a.m. on Saturdays and 7:20 a.m. on Sundays, while westbound service began at 7:50 a.m. on Saturdays and at 8:30 a.m. on Sundays. With the change, eastbound service would begin at 4:45 a.m. on Saturdays and 5:20 a.m. on Sundays, and westbound service would begin at 6:00 a.m. on Saturdays and 6:30 a.m. on Sundays. The change would be made since ridership on the first trips of the day indicated demand for earlier service. The span of Sunday service was extended again on September 7, 2003, with the last trip from Staten Island leaving at 10:10 p.m. instead of 9:45 p.m., and the last trip from Brooklyn leaving at 11:30 p.m. instead of 11 p.m.. The MTA announced in June 2012 that the S79 would be converted to a Select Bus Service route, as the S79 was Staten Island's busiest bus route. By 2017, the route was so crowded that numerous local elected officials were advocating for the MTA to increase the frequency of S79 bus service. Traffic cameras were mounted onto S79 buses in late 2022 as part of a pilot program to ticket drivers who were using bus lanes illegally. In January 2023, the MTA announced that bike racks would be installed on the front of S79 buses. ==References==
