Construction Begins On Tremont Avenue Busway In Tremont, The Bronx

Construction is underway on the Tremont Avenue busway, a mile-long bus-priority corridor in Tremont, The Bronx. Announced Wednesday by Mayor Zohran Mamdani and New York City Department of Transportation Commissioner Mike Flynn, the project will deliver the borough’s first busway, serving 39,000 daily riders on the Bx36. The redesign will also bring safety upgrades to eight intersections and 0.26 miles of additional bus lane. The corridor runs along Tremont Avenue from Webster Avenue east to Southern Boulevard, with connections to eight subway lines, Metro-North Railroad, and several local bus routes.

The project arrives after a years-long stall. NYC DOT presented its final proposal for the busway in March 2025 and planned to begin installation that spring, before the prior administration paused the project, citing insufficient community support. The Mamdani administration revived the plan last month as part of Next Stop: Fast Buses, Better Service, the joint action plan from the city, New York State, and the MTA targeting faster, more reliable service on 175 bus routes, and identified Tremont Avenue as one of its Priority Corridors.

The street redesign will include an eastbound busway from Third Avenue to Southern Boulevard, a westbound busway from Southern Boulevard to Belmont Avenue, and an offset shared bus and bicycle lane eastbound from Webster Avenue to Third Avenue. The busway will operate seven days a week from 6 a.m. to 8 p.m., with through access limited to buses, trucks with six or more wheels, emergency vehicles, and Access-A-Ride vans; all other vehicles, including taxis and for-hire vehicles, may enter from side streets for local access but must exit at the next available right turn. Enforcement will come from stationary cameras along the route, bus-mounted cameras, and the NYPD. NYC DOT will also adjust curb regulations and install new loading zones to reduce double parking, while the shorter westbound segment will preserve vehicle access to every block for pick-ups, drop-offs, and deliveries.

Tremont Avenue is a Vision Zero Priority Corridor, with among the highest rates of pedestrian deaths and serious injuries per mile in the borough. Between 2020 and 2024, nearly 630 people were injured in crashes along the corridor, an average of two per week, with 46 suffering severe injuries and four killed. Safety redesigns at eight intersections, including Tremont Avenue at Webster Avenue, Third Avenue, and Southern Boulevard and Crotona Parkway, will feature painted sidewalk extensions that shorten pedestrian crossing distances and naturally slow turning drivers, reinforced with plastic flex posts, granite blocks, and bicycle parking.
