The Bronx's first dedicated busway is scheduled to launch on Tremont Avenue on 19 September 2026. The date turns a July announcement into a direct delivery record for the Mamdani administration and NYC DOT.
The busway will run eastbound from Third Avenue to Southern Boulevard and westbound from Southern Boulevard to Belmont Avenue. It will operate every day from 6am to 8pm for buses, qualifying trucks, Access A Ride vehicles, emergency vehicles and bicycles.
Passenger vehicles and taxis can still enter for local access, pickups and drop offs, but they must leave at the next available right turn. Parking remains permitted under posted rules. The city says the corridor serves 39,000 daily riders and that Bx36 buses can move at less than 5 mph during rush hour.
This updates the existing Mamdanistan bus priority page, which already recorded the Tremont project and Broadway bus lane. The question is no longer only whether the busway was advanced. It is whether the launch occurs on time and produces faster, safer and more reliable trips.
What changes on Tremont Avenue
Red roadway markings and turn rules will reserve through travel for permitted vehicles during operating hours. Passenger vehicles retain access to each block but cannot use the busway as a through route.
The redesign also includes painted sidewalk extensions, intersection safety work and a shared bus and bicycle lane east of Third Avenue. NYC DOT says the project is intended to improve deliveries as well as bus movement and street safety.
The launch follows more than 40 outreach meetings and events recorded by NYC DOT. The first weeks should include clear signs, driver information and published enforcement guidance.
The delivery record
A launch date is stronger evidence than another general promise, but it is not the outcome. The administration should publish before and after Bx36 speeds, travel time reliability, crashes, blocked lane reports and enforcement activity.
The strongest transit case combines affordability with time. Fare policy affects household costs. Bus priority affects whether riders lose hours in traffic. City Hall controls much of the street design while the MTA controls service and fares.
The Broadway bus lane remains useful comparison evidence. The Tremont record should now show whether a dedicated Bronx busway can deliver similar or better gains at a larger daily scale.
Public record
- Confirm the busway opens on 19 September 2026 and publish any delay immediately.
- Publish Bx36 speeds and travel time reliability before launch and at regular intervals afterward.
- Track crashes, pedestrian injuries and cyclist injuries along the redesigned corridor.
- Report warnings, camera enforcement and blocked busway incidents.
- Show how rider feedback changes signs, loading zones, access rules or enforcement after launch.
What to check next
The first test is whether the busway opens on the stated date.
Daily riders need verified travel time improvement, not only a new road layout.
Local access, loading, pickups and parking rules need clear public signs.
The city should publish injury and collision results beside bus speeds.
