Routes 309 and S09

Routes 309 and S09 are two bus routes that run from 42nd Street Bus Terminus to either Bay Ridge - 95th Street, Burwood (309 from 8.30am to 10.15pm) or Wynn Hotel Duchessville (S09 from 8.30am to 10.15pm; 309 from 10.15pm to 8.30am). The S09 has no overnight service, with the overnight service supplanted by the 309 running 24 hours. The S09 is a free shuttle, while the 309 is a fare-based all stops service. The S09 was started when the Wynn Hotel in Duchessville was completed in 2007. The 309 is older, tracing its roots to March of 1947.

Depots
Brookfield bus depot (V) and Carina bus depot (C) share the 309, while Brookfield bus depot (V) is the only depot that operates the S09.

Fleet
The 309 is operated by single-decker buses of Mercedes-Benz and Scania, and the Volvo B12BLE three-axle 14.5m buses.

Coronavirus
The S09 was temporarily suspended until July to prevent the spread of coronavirus in Duchessville. From March to July, the 309 ran only to Bay Ridge - 95th Street all day.
