YIMBY Observes the Rising Philadelphia Skyline from the Walt Whitman Bridge

The Walt Whitman Bridge presents an excellent vantage point for a showcase of the major projects that are rising in the Philadelphia skyline. Today Philadelphia YIMBY shares photos of the city taken from the suspension bridge, which is one of the largest structures that spans the Delaware River, with towers that stand 378 feet tall. The west end of the bridge is situated just to the north of the Port of Philadelphia, from where it heads east to Gloucester City, New Jersey on the other side of the river and provides access to Camden, Trenton, Atlantic City, and beyond. The route to New Jersey features a view of billboards that annoyingly block the skyline from the Philadelphia side, the Southwark Generating Station and its four white chimneys. However, when heading west towards the city, the bridge offers panoramic views of the skyline.

Looking at the PNB Building at One South Broad Street in Center City

The PNB Building at One South Broad Street in Center City was originally built as a massive addition to the Wanamaker’s at 1300 Market Street, just to the west of the department store. The building was originally called the Lincoln-Liberty Building, though today the structure is known as One South Broad. The 465,000-square-foot building stands 28 stories tall and rises to a height of 478 feet. The tower was designed by John Torrey Windrim, who also designed the Franklin Institute, which was completed in 1934. The building features a wide profile from the east and west and a setbacked crown that steps up to a bell tower that holds the 17-ton Founder’s Bell. The tower’ cornerstone was placed on October 1, 1931, shortly before the nearby Wanamaker Men’s Store opened over a week later on October 12, 1932.

Remembering the Unbuilt Centennial Tower in Fairmount Park, West Philadelphia

During the planning for the Centennial Exposition of 1876, expo organizers put forth a bold proposal for an incredibly tall structure called the Centennial Tower in Fairmount Park, where two buildings still remain from the expo. The tower was planned at 1,000 feet tall, well before any skyscrapers were built in the city. The tower would have risen as large cross-braced tube that slims down at the top, capped with a short cone top and lightning rod, and would have featured four observation levels. The metal structure was designed by Clarke, Reeves and Company, which had also designed an older bridge that stood at then site of the current Girard Avenue Bridge.

Philadelphia YIMBY Presents Massing Renderings of the 1975 Skyline

In the 1970s the Philadelphia skyline was on the rise, with bulky new office towers being constructed throughout Center City. At this time, the “Gentlemen’s Agreement” was untouched, as every structure stood below the height of the statue of William Penn at the top of City Hall. New high-rises were adding substantial amounts of office space and dominated the previous structures that stood out in the skyline, and featured various designs with stone, metal, and glass cladding. Philadelphia YIMBY presents massing renderings of the skyline as it stood in 1975, when Brutalist architecture dominated much of the financial district, including the area around City Hall.

Philadelphia YIMBY Presents Massing Renderings of Two New CHOP Towers

A month ago, the Children’s Hospital of Philadelphia unveiled two new towers that are part of a $3.4 billion plan that will add considerable bulk to the University City skyline in West Philadelphia. On the University City side, the University-City-Tower at the presumed address 3401 Civic Center Boulevard will rise across the street from the CHOP Buerger Center for Advanced Pediatric Care at 3500 Civic Center Boulevard. On the Southwest Center City side, 690 Schuylkill Avenue will stand to the northeast of the CHOP Robert’s Center for Advanced Research as the tower, right next to the iconic South Street Bridge.
