Context paragraphs:
Race–Vine station: Race-Vine is a rapid transit passenger rail station on SEPTA's Broad Street Line.  It is located at 300 North Broad Street (PA 611) in the Center City district of Philadelphia, and serves both local and express trains.  The station is named after Vine Street, which today acts as frontage roads along Interstate 676 and nearby Race Street, although the given address is closer to westbound Vine than Race.  This stop is also used as the Pennsylvania Convention Center stop for the Broad Street Line (signs will direct passengers to the appropriate exits, although riding the Broad Street Line one stop further south to City Hall and then connecting to the Market–Frankford Line East toward Frankford and then exiting at 11th Street station will bring passengers right inside the Convention Center and The Gallery at Market East).

Pendleton railway station: Pendleton (Broad Street) railway station was a railway station serving Pendleton, a district of Salford.  It was located on Broughton Road (A576) just behind St. Thomas' Church ("Pendleton Church").  It was about 100 yards further up Broughton Road from Pendleton Bridge railway station and nearer Pendleton Church and Broad Street (A6).  This station was known as Pendleton Broad Street due to its closeness to the A6 Broad Street some 100 yards away.  It was on the Manchester Victoria to Wigan Wallgate line with a spur to the Manchester Victoria to Bolton line so trains to Bolton used it after the closure of Pendleton Bridge in 1966, and "Broad Street" was then dropped from its name.

SNCI Tower: The SNCI Tower is a planned apartment skyscraper in New York City, New York.  The building is planned to rise 289.6 metres (950 ft) in the city's TriBeCa district, with 57 floors.  The building was proposed in mid-2011.  The SNCI Tower was designed by the solus4 architectural firm and LeMessurier Consultants.

Broad Street Tower: Broad Street Tower (also known as 212–223 Broad Street by its address) is an approved 134-metre skyscraper for Broad Street, Birmingham, England.  It is designed by DTZ Pieda Consulting and Level Seven Architects.

Nevada City Firehouse No. 2: Nevada City Firehouse No. 2 is a historic firehouse located at 420 Broad Street in Nevada City, California.  Built in 1860-61, the firehouse was the first built in Nevada City.  At the time, Nevada City had two factions competing for public funds for a firehouse: the Broad Street fire company and a group based on Main Street.  While the Main Street company officially organized a day before the Broad Street company, the Broad Street firehouse had more private funding and was completed first, and hence Firehouse No. 2 became the first in the city.  The firehouse features a two-story portico in front and a Greek Revival cornice.

45 Broad Street: 45 Broad Street is a skyscraper under construction in the Financial District of Manhattan.  The building will be entirely residential, and is being developed by Madison Equities on Broad Street.

Artspace in Richmond, Virginia: Artspace in Richmond, Virginia began in 1988 and is a non-profit, artist-run 501-C3 gallery and performance space currently located south of the James River in the Manchester area of the city at Zero East 4th Street in the art complex Plant Zero.  The gallery began as Artspace 1306 in a donated, rent-free space at 1306 Cary Street in Richmond's historic Shockoe Slip.  Upon the loss of its free space, the gallery moved to North 18th Street in Shockoe Bottom, retaining its original name of Artspace 1306.  The gallery's next move as Artspace 1306 was to a much larger building at 6 East Broad Street in Jackson Ward, and the name of the gallery was changed at the request of the Richmond post office to Artspace, removing its former street number to prevent confusion at the new location.  Artspace was the first of the Shockoe Bottom art galleries incorporated as non-profit organizations to locate on Broad Street, and it became an anchor gallery for Richmond's First Friday Art Walk and a popular and long-lasting venue for the Arts and Cultural District formed for Broad Street and Downtown Richmond.

Broad Street Line: The Broad Street Line (BSL)—also known as the Broad Street Subway (BSS), Orange Line, or Broad Line—is a subway line owned by the city of Philadelphia and operated by the Southeastern Pennsylvania Transportation Authority (SEPTA).  The line runs primarily north-south from the Fern Rock Transportation Center in Upper North Philadelphia to Pattison Avenue in South Philadelphia; the latter station provides access to the stadiums and arenas for the city's major professional sports teams, about a quarter mile away.  It is named for Broad Street, the street under which it runs for almost its entire length.  The line, which is entirely underground except for the northern terminus at Fern Rock, has four tracks in a local/express configuration from Fern Rock to Walnut-Locust and two tracks from Lombard-South to the southern terminus at AT&T Station (formerly Pattison Station).  It is one of only two rapid transit lines in the SEPTA system overall alongside the Market–Frankford Line.

Lombard–South station: Lombard–South is a subway station on SEPTA's Broad Street Line, located at 500 South Broad Street, at the intersection of Broad Street and Lombard Street in the South Philadelphia area of Philadelphia, Pennsylvania.  It serves only Broad Street Line local service trains and consists of one platform.

Military Park (NLR station): Military Park Station (formerly Broad Street Station) is an underground station on the Newark City Subway Line of the Newark Light Rail.  The station is owned and service is operated by New Jersey Transit.  The station is located at the intersection of Raymond Boulevard, Park Place and Broad Street in Downtown Newark at Military Park.  The station was opened in 1935 and called Broad Street Station.  It was renamed so only one station in the system would carry the name Broad Street when Downtown Newark's stations (Penn Station and Broad Street) were connected by the Newark Light Rail Line.  The station is decorated with beige tiles and colored tiles for borders, mosaics and street indicator signs.  This station is not wheelchair accessible, but the adjacent stations, Penn Station and Washington Street, are.
