August 2019 Update

One year after launching the redesigned Staten Island Express Bus Network, data is showing that service between Manhattan and Staten Island has steadily improved across all metrics. Get the presentation here.

Here’s some of what we’ve accomplished.

MORE TRIPS: We added 121 trips every weekday, 76 trips every Saturday and 50 trips every Sunday compared to the previous network, including off-peak and weekend service.

MORE ROUTES: We added three new routes – the SIM11, SIM33C and SIM9

MORE SERVICE: We extended route spans – increased the amount of time a route operates – on the SIM1, SIM34 and SIM4/4C

FASTER BUSES: In July 2019, average SIM bus speeds were 5.5% faster, or 17.2 mph, compared to 16.3 mph in June 2018 under the old network. Average SIM speeds are going up, to 17.2 mph year-to-date from 15.7 mph for the same period in 2018.

MORE RELIABLE: In spring 2019, 71.2% of customers finished their trip within 5 minutes of the scheduled time, up from 63.9% in spring 2018.

SHORTER WAITS: In July 2019, SIM customers waited for shorter periods -- 1m15s beyond their schedule wait time -- at stops compared to 1m40s under the old network last July.

LESS CROWDING: In July 2019, 30 weekday trips and 2 weekend trips had standees, compared to 42 weekday trips and 5 weekend trips under the previous network in July 2018.

IMPROVED TRANSIT PRIORITY: NYC Transit and MTA Bridges & Tunnels are working closely with NYPD and NYCDOT to keep traffic moving near the Hugh L. Carey Tunnel during evening peak hours. The multi-agency collaboration began in fall 2018 has led to faster bus speeds by 29%, increasing to 8.2 mph in July compared to 6.3 mph last fall.

HARNESSING NEW TECHNOLOGY: Seat availability information for Staten Island express buses is now available via the MYmta smartphone app. The technology was first tested by a select group of SIM customers who provided feedback during the bus network redesign, and the feedback from SIM customers will guide the larger rollout of the technology to include all MTA buses.


We've created updated schedules, maps, and timetables to help understand the new network.

Project Background

Staten Island’s express bus service started in the 1960’s. Since then, population, work trends, and the number of cars on the road have shifted. For a while, changes to the network happened piecemeal. In 2015, the MTA launched a comprehensive study to find out the best way to improve the network and provide better service. Data analysis and input from more than 3,000 riders as well as bus operators, elected officials, and local community leaders led to the creation of the redesigned network.

The new network is designed to address slow speeds and unreliability. The updated routes concentrate service where possible to streets with bus priority and are, on average, shorter and spend less time on Manhattan streets. They have fewer turns and have more space in between bus stops. Riders’ benefits include the following:

  • Simplified service to Manhattan
  • More direct routes on Staten Island
  • Fewer stops to speed up trips
  • Expanded off-peak and weekend service to Manhattan
  • Streamlined routing to either Midtown or Downtown Manhattan
