On October 29, 2023, Suffolk Transit introduced the
Reimagine Transit Initiative, a full redesign of the bus network. As part of this redesign, there is daily service system-wide with local buses running weekdays until 10 p.m. and to 8 or 9 p.m. on weekends.
All current routes Most routes west of
Port Jefferson and
Patchogue are scheduled with 30 minute headways (60 minutes on routes 3, 10 and 15) during weekdays until at least 6:00 p.m. On all routes from Port Jefferson and Patchogue and to the east, including the north-south routes between those two terminals, there are 60-minute headways (except for 30-minute headways on routes 51 and 66). All weekday late evening and weekend service runs on 60-minute headways. Route numbers (not including 110) are lower in the western portion of the county (1 through 17) and higher in the middle and eastern portions (51 through 92). Odd-numbered routes are generally oriented north to south, with even numbers west to east. Timed connections between routes can be made at
Long Island Rail Road stations in
Amityville,
Bay Shore,
Brentwood,
Central Islip,
Patchogue, and
Riverhead, and at the
Smith Haven Mall. SCT also runs two
on-demand systems on the
South Fork in
Southampton and in
East Hampton operated by
Hampton Jitney and
Via Transportation that replaced the former 10A, 10B, and 10C bus routes. The two on-demand zones connect with Route 92 in Southampton,
Sag Harbor, and East Hampton. The zones operate 7 days a week between 6 AM and 8 PM, including holidays. In early June 2024, SCT added a new route, the 56, running between Smithtown Railroad and Kings Park Manor. In the following table, routes highlighted in red have 30-minute service on weekdays, with non-highlighted routes having 60-minute service.
History of current routes These current routes are replacements and reconfigurations of the
previous routes that were prefixed with an "S" label, although
more localized routes did not have the prefix. The prefix denoted Suffolk County, akin to route labeling in other transit systems around the region. See further down in this article for historical information about all of the former routes. Most of the routes listed in this table replaced all of the former routes on October 29, 2023.
Former routes - S1 to S94 Most of these routes were reconfigured and replaced by the routes listed above on October 29, 2023 in conjunction with the
Reimagine Transit Initiative.
