Broad Street & Allen Street Intersection in Rochester — Live Webcam

The intersection of Broad Street and Allen Street is located in downtown Rochester, New York, at the junction of several historical eras of urban development. Broad Street was once the aqueduct of the Erie Canal and is now a four-lane urban arterial road, while Allen Street is a local street connecting the intersection to the Susan B. Anthony District. The webcam in real time shows a transportation hub that is undergoing a massive transformation as part of one of the most ambitious infrastructure projects in recent years.

Historical Significance: From Canal to Boulevard

Rochester's Broad Street is not just a street but a structure built over one of the key engineering landmarks of the Erie Canal. The stone aqueduct that carried the river over the Genesee River was built in the 1820s and long defined the look of the city's central area. After the canal was rerouted in the 20th century, the aqueduct served as the foundation for the Rochester Subway underground rail system and was later converted into a roadway. Detailed documentation of this structure can be found on HistoricBridges.org.

Allen Street, on the other hand, was laid out during the early formation of the village of Rochester and is named after one of the first landowners in the area. Its intersection with Broad Street has always served as an important access point from the residential Third Ward to the downtown business district and the Genesee River waterfront.

The Susan B. Anthony District and Its Context

The intersection of Broad Street and Allen Street lies within the boundaries of the Susan B. Anthony Historic District, named after the famous suffragist and civil rights activist. The district formed in the 19th century as a working-class neighborhood with dense row housing, small factories, and workshops. After the construction of the elevated Inner Loop highway in the 1960s, the area was physically cut off from the rest of the city, leading to decades of decline and disinvestment. The Broad and Allen intersection found itself right at the edge of this artificial boundary — on one side an active arterial road, on the other a deteriorating residential environment.

Inner Loop East Project: Converting a Highway into a Boulevard

The turning point came with the launch of the Inner Loop East project — a massive highway reconstruction that transformed it into a standard surface-level boulevard. Completed by 2020, the project demolished the elevated portion of the expressway and restored the historical connectivity of the street grid. Removing the viaduct opened up an area that had previously been inaccessible to pedestrians and cyclists, and allowed the Susan B. Anthony District to be reconnected with downtown Rochester.

For the intersection of Broad Street and Allen Street, this meant a fundamental change in its transportation role. A location on the periphery of an expressway became a fully integrated urban street network node, oriented toward all road users — not just motorists.

Traffic Characteristics of the Intersection

Broad Street is classified as an urban arterial and was historically part of New York State Route 31. After the reconstruction, the roadway underwent a so-called "road diet": the number of lanes was reduced from four to two with the addition of a center turn lane and dedicated bike lanes. Allen Street remains a two-way local street with low traffic volume.

The intersection is equipped with traffic signals and has a fairly typical level of congestion for the central part of the city. During peak hours, waiting times at signals can increase, but the demolition of the Inner Loop viaduct and the redistribution of traffic flows have reduced peak loads compared to the previous configuration. Traffic volume on Broad Street in the central segment is estimated at roughly 15,000–20,000 vehicles per day — a typical figure for an urban arterial of this class.

Engineering Features and Design

The redesign of the intersection as part of the Inner Loop East project implemented the Complete Streets principle — streets that are safe and convenient for all categories of users. ADA-compliant ramps were installed, high-contrast crosswalks were marked, pedestrian refuge islands were added, and traffic signals with LPI (Leading Pedestrian Interval) functionality were introduced, giving pedestrians a head start before vehicles begin moving.

Particular attention should be given to the green infrastructure integrated into the street space. Bioswales and permeable pavement provide natural stormwater drainage, reducing the burden on the city's sewer system. For downtown Rochester, this approach was pilot and subsequently replicated on other streets. Design also took into account restrictions imposed by the State Historic Preservation Office (SHPO), as Broad Street sits directly atop the historic aqueduct.

Surroundings: What's Nearby

Within walking distance of the Broad Street and Allen Street intersection are several significant pieces of city infrastructure. Upstream along the Genesee River is the Blue Cross Arena complex — a major sports and concert venue that draws significant traffic flows in the evening hours. Downstream are pedestrian and bicycle trails along the river, connecting the intersection to the waterfront and the Frederick Douglass – Susan B. Anthony Memorial Bridge (formerly the Platte Street Bridge).

On Broad Street itself, east of the intersection, sections of commercial development with businesses and offices have been preserved. Westward — toward the river — stands Rochester City Hall and the administrative offices of Monroe County. The area continues to feel the effects of the Inner Loop removal: previously vacant lots beneath the viaduct are now being developed for mixed residential and commercial use.

What You See on the Camera

The webcam is positioned to capture the entire intersection of Broad Street and Allen Street. The frame shows the roadway of Broad Street with its lane markings and traffic lanes. On the left, Allen Street passes by with an adjacent green zone. In the background, a viaduct or overpass structure crossing Broad Street is visible. The right side of the image may be partially shaded — this is a reflection from the camera's protective glass or part of its housing. In the top left corner, a text overlay reads "Broad and Allen." During wet weather, puddles and wet asphalt are noticeable on the roadway, adding realism to the real-time picture.
