Navigating upper Manhattan and the western Bronx without a car relies heavily on local transit corridors. Among these, the Bx3 bus serves as a crucial spine connecting Washington Heights to Riverdale. Operating under the Metropolitan Transportation Authority (MTA), this route links major residential communities, educational institutions, and heavy rail transit lines across roughly 25 stops. Understanding its pathway, key intersections, and operational quirks helps daily commuters avoid common transit delays.
The route bridges the George Washington Bridge Bus Station in Manhattan with the Kingsbridge neighborhood in the Bronx. Rather than taking a straight north-south highway, it weaves through dense urban corridors, making it a lifeline for riders who would otherwise face complicated multi-seat subway transfers. Whether you're commuting to work, attending classes near University Avenue, or visiting family in Riverdale, knowing how the Bx3 operates saves time and frustration.
Route Overview and Terminals
The Bx3 runs between its southern terminal at Broadway and West 179th Street in Washington Heights and its northern terminal at West 238th Street and Broadway in Riverdale. The entire trip spans approximately 25 stops and takes between 35 and 45 minutes depending on traffic conditions along University Avenue and Sedgwick Avenue.
Heading northbound from Manhattan, the bus leaves the vicinity of the George Washington Bridge Bus Station, heading east along West 181st Street before turning onto University Avenue. It tracks University Avenue northward through Morris Heights and University Heights, passing major cross streets like West Burnside Avenue and West Fordham Road. Near Kingsbridge Road, the bus makes a distinct dogleg transition onto Sedgwick Avenue, navigating Kingsbridge Heights before finishing its run via Fort Independence Street and West 238th Street to Broadway.
Southbound trips reverse this exact sequence, funneling commuters from the Bronx back down toward the major subway connections in upper Manhattan.
Key Intersections and Connections
One reason the Bx3 is so heavily relied upon is its integration with the wider New York City transit grid. Riders can transfer to multiple subway lines and other bus routes along the way.
- Washington Heights Terminal: At the southern end near Broadway and 179th Street, riders gain access to the 1 subway station at 181st Street, as well as numerous other Manhattan and cross-river bus lines operating out of the George Washington Bridge infrastructure.
- University Avenue Corridor: This middle stretch acts as a major artery through the west Bronx. It intersects with high-volume crosstown routes, including buses running along West Burnside Avenue and West Fordham Road, providing access to commercial strips and academic hubs.
- Northern Terminal (238th Street): The northern terminus sits steps away from the 238th Street station served by the 1 train, allowing seamless transitions between local bus service and rapid transit into midtown Manhattan or deep into the Bronx.

Schedule Patterns and Frequency
The Bx3 operates seven days a week, with early morning service beginning around 6:11 AM on weekdays. Depending on the time of day, buses arrive at regular intervals:
- Peak Hours: During morning and evening rush hours, headways tighten significantly, with buses scheduled roughly every 6 to 10 minutes.
- Off-Peak and Weekends: Midday and weekend frequencies stretch out, ranging from 10 to 20 minutes between arrivals. Late-night service runs past midnight, though headways widen considerably during the overnight hours.
Because traffic congestion along University Avenue and near the George Washington Bridge heavily impacts street-level transit, relying solely on static timetables can lead to long waits. Real-time tracking tools like MTA Bus Time or third-party apps are essential for checking actual vehicle locations before heading to the stop.
Common Commuter Challenges
Riding the Bx3 comes with typical urban transit hurdles that regular passengers learn to navigate over time.
- Traffic Bottlenecks: University Avenue and the approaches to the George Washington Bridge experience severe vehicle backups during peak commuting windows. A trip that takes 35 minutes midday can easily stretch past an hour during heavy rush-hour gridlock.
- Crowding During School Hours: Because the route passes several local schools and universities, afternoon dismissals can crowd buses quickly, particularly along the University Avenue segments.
- Weather Disruptions: Snow or heavy rain in upper Manhattan and the Bronx frequently slows down local traffic, causing bunching where two buses arrive back-to-back followed by a long gap.
