Manhattan to Staten Island

Most routes travel to and from Staten Island via the Verrazzano–Narrows Bridge, Gowanus Expressway, and Hugh L. Carey Tunnel into Lower Manhattan. Some routes operate through New Jersey via the Goethals Bridge, New Jersey Turnpike, New Jersey Route 495, and Lincoln Tunnel to directly serve Midtown Manhattan.

On August 19, 2018, all of the Staten Island-Manhattan express bus routes were redesigned to offer simpler and direct routes, fewer stops to speed up the trips, and additional service for off-peak hours and weekends. The new routes originally planned consists of 21 express routes: 11 traveling to Midtown, 8 traveling to Downtown and 2 traveling to Greenwich Village via Battery Park City. The previously used "X" routes have been dropped in favor of "SIM," or Staten Island to Manhattan, routes. This was the result of the two-year Staten Island Bus Study conducted by MTA, launched in 2015, which analyzed trip performance data, ridership profiles and extensive customer input, to determine the most effective way to reconfigure the network.http://nymta.civicconnect.com/ "We're Speeding Up Staten Island" MTAhttps://www.silive.com/news/2018/06/mta_board_approves_express_bus.html "MTA board approves express bus redesign, new network to take effect Aug. 19" silive.com - June 21, 2018

All routes are operated by New York City Transit. All routes run during rush hours in the peak direction. In addition, the SIM1C, SIM3C, SIM4C and SIM33C provide off-peak weekday and weekend service, and the SIM1C provides overnight service. These four -C routes cover most stops in Manhattan served by other routes during peak hours.
