4211 Broadway, 2001. At the I-95 exit on the George Washington Bridge, U.S. Route 9 merges with Broadway. U.S. Route 9 (US 9) is the longest north-south U.S. Highway in New York. It begins in Laurel, Delaware, crosses from New Jersey to New York City via George Washington Bridge, intersecting Broadway at 179th Street and continuing through the Bronx. US 9 terminates a few miles south of the U.S./ Canada border, at a junction with Interstate 87 which connects New York City to Montreal.

Though actually triangular, Mitchel Square is a small urban park that features the war memorial seen here. The plot was initially dedicated as a public space in 1911 and named Audubon Square. On February 8, 1919, the square was renamed in honor of John Purroy Mitchel. Mitchel was elected the youngest mayor of New York City (a record which still stands) in 1913. The "Boy Mayor" was known for his idealism and (perhaps uncommon in politics) honesty. Following his mayoral term (he lost a bid for reelection in the primaries), he enlisted in the Army Air Corps. In 1918 while on a training flight in Lousiana, Mitchel fell from his plane and died. The city (and state) mourned and eulogized the former mayor, naming this park after him, erecting a memorial at Fifth Avenue and East 91st Street, and naming a Long Island airfield for him. Theodore Roosevelt wrote of the man, “No stauncher American, no abler and more disinterested public servant, and no finer natural soldier than Purroy Mitchel was to be found in all our country.” Four years after the park's renaming, this World War I memorial sculpture was installed. Dedicated on May 30, 1923, and designed by Gertrude Vanderbilt Whitney, this public arts still stands on the north side of the park, while the south side remains benches and rock outcroppings.

563 West 169th Street, ca. 1932.

White Tower Hamburger, 1933. White Tower Hamburger was a chain of fast food restaurants created as a copycat or imitator (if we are being generous) of White Castle. Founded in Milwaukee in 1926, they hired away White Castle employees, barely tweaked the chain's slogan, and mimicked the crenellated building design. By the 1950s White Tower had more than 250 locations all across the country., largely in urban areas. Despite the inevitable copyright lawsuit, the last batch of original White Towers remained in business through the 1980s. (A single location is still open in Toledo, Ohio, though it is long divorced from the original owners). New York City was home to at least a half a dozen White Tower Hamburger locations. This castle-like building at Broadway and West 167th Street is no longer extant, but at least one original White Tower building remains in Woodside, Queens.

563-565 West 170th Street, 1932. The building at left (no.565) remains, though you might not realize it. Looking at the current structure directly from the sidewalk in front, it looks to be a late 20th century structure: simple, red brick, no style. But, if one walks just slightly down the block to the east and looks back, the wood-frame house, complete with peaked roof, is visible.

22nd Regiment Armory, date unknown. The massive brick Classical Revival structure with Romanesque Revival elements served as the headquarters for the 22nd Regimental Armory. Completed in 1911 to the designs of the firm of Richard Walker and Charles Morris. The 22nd Regiment was downsized, merged, and moved around in the mid 20th century. The drill hall became for a time a track-and-field venue for the city's schools (having hosted athletic events even while occupied by the national guard). In the 1980s, the huge building served as a city homeless shelter. In the 1990s Dr. Norbert Sanders (the only New Yorker to ever win the city's marathon) raised $25 million to refurbish the building. Today it houses the National Track & Field Hall of Fame, a large after-school program, and the Millrose Games, the country’s best-known indoor track-and-field event.

J. Hood Wright Park, May 18, 1924. Haven Avenue, south from West 176th Street, showing several new apartments under construction. The far two, including the frame residence were removed subsequently and their sites are now a part of J. Hood Wright Park. At the right is W. 177th Street, continuing its winding way downhill to Riverside Drive.

Highbridge Park Center, June 20, 1940. The land next to the 1848 High Bridge is an appropriate location for a municipal swimming pool, being the original location of the old High Bridge Reservoir. The pool and play center opened July 14, 1936. The play center was designed in the same simplified Art Moderne style of the other 1936 pool houses. The building is particularly notable for its ashlar construction. Ashlar construction means the stones used to create the walls were finely and uniformly cut into their shape and as such create very thin joints between blocks. This type of masonry is visible in the long retaining wall that runs along Amsterdam Avenue. Another unique feature of the building was the lobby murals by artist Charles Clarke. The pool facilities have been renovated a number of times since the 1960s.The earliest work either covered up or destroyed the lobby murals. Along with a number of the other WPA pools, High Bridge underwent a renovation project in the early 1980s that updated the heating, ventilation, electrical, and filtration systems and made the facilities handicap accessible. More recent work on the pool occurred in the late 1990s and in 2015 the actual High Bridge itself was reopened to the public after being closed for more than 40 years.

Chelsea Methodist Episcopal Church; May 23, 1929. In the early part of the 20th century, the Chelsea Methodist Episcopal Church, Parish House, and offices were located at the intersection of 178th Street and Fort Washington Avenue. While the church orginally worshipped at 331 West 30th Street in Chelsea, the congregation relocated uptown in 1907. Upon moving, the church held services in its new Washington Heights building until the late 1920s, when it was razed to make way for the George Washing Bridge.

109 Wadsworth Avenue, May 27, 1927. 109 Wadsworth Avenue at the N.E. corner of West 178th Street, showing what was then the synagogue of the Congregation of Mount Sinai Anshei Emeth.

Sobol Gas Station and Fort Washington Presbyterian Church, 1927. Ira and Ida Sobol were Jewish immigrants who arrived in New York in the early 20th century. Working in the new and booming car industry, the family was able to purchase a gas station. The business was a success, and Sobel Brothers became a chain of service stations in the five boroughs, though perhaps most concentrated in Flushing, Corona, and northern Queens. Today this small plot, a triangle between Broadway, Wadsworth Avenue and 174th Street remains a gas station. The steeple seen behind the gas station is the Fort Washington Presbyterian Church. Founded in 1913 through the merger of the West Presbyterian and Park Presbyterian Churches, the new congregation built a fine neo-Georgian edifice on Wadsworth Avenue. The church with the tall bell tower was designed by Thomas Hastings of the venerable firm of Carrère & Hastings. The congregation here has changed with the demographics of the local community. Since 1948 Spanish-language services have been held here and today the church membership is largely Dominicans and Puerto Rican.

This is the northwest corner of West 173rd Street and Broadway. The billboard advertises (and requests funds) for a new church called the Broadway Temple. This massive planned structure was the brainchild of Reverend Christian Reisner, the leader of a Washington Heights Methodist congregation. Upon learning in 1923 that their current place of worship was to be demolished for the planned George Washington Bridge, Rev. Reisner decided their next home would be a ”magnificent advertisement for God’s business.” This proposed church by architect Donn Barber was to include two 12-story apartment buildings flanking a soaring central tower, complete with a 75-foot-high rotating cross at the top. The church was to seat more than 2,000 and have a basement space with a gym, bowling alley, and pool. Needing $4 million for his church, the reverend sought funds from New York's wealthiest (John D. Rockefeller, for one) and its regular folks (the billboard urges passers-by to help out with 5% bonds). By the start of the Depression, the two Deco apartment houses had been completed, but the church itself was far from its planned 725 feet. Stalled until the 1940s because of debt, construction on the much more restrained edifice (only three stories as compared to 40) was begun again in 1947 and the temple was completed in 1952 (with no rotating cross). The final design was completed by Shreve, Harmon and Lamb, the firm that designed the Empire State Building.
