The American Commerce Center is a supertall skyscraper approved for construction in Philadelphia, Pennsylvania. At 1,510 feet (460 m) tall with 63 floors, the building would dominate the Philadelphia skyline, standing over 500 ft (150 m) taller than Philadelphia's current tallest building, the recently completed Comcast Center.^[1] The 1,510 ft (460 m) office tower, which would rise on the 19th Street side of Arch Street, and be connected to a 473 ft (144 m), 26 story hotel tower and public plaza along the 18th Street side of the block.^[3] The connection consists of a multi-story skybridge with a garden on top.^[2]

Of several supertall skyscrapers proposed for Philadelphia (including the Center City Tower and an early version of Comcast Center), this would be the first to be constructed.^[5] I

On June 19, 2008, Philadelphia City Councilman Darrell Clarke introduced changes for the zoning legislation around 18th and Arch Streets which was the first step towards building the tower.^[6] On November 18th, 2008, the City Planning Commission signed off on legislation needed for the zoning changes. According to the Philadelphia Daily News, "the developers will have to come back for approval of their building plan if Council passes the zoning bills." ^[7] On December 11, 2008, the zoning changes in question were unanimously approved by City Council. ^[8] Construction was slated to begin in Spring 2009 at the earliest, though the proposed building still lacks an anchor tenant.

The tower's observation deck would be the tallest in the city. When it is completed, it will be the third tallest building in the United States of America. The building slightly resembles One World Trade Center.
