Ever since the 500-foot-plus height limit was erased after One Liberty Place went up, developers rushed to construct buildings taller than the prior boundary. Designed by WZMH Architects, the twin towers of the Independence Blue Cross Tower were originally proposed to stand next to each other, rising 625 feet and 45 stories tall at 1901 Market Street and at 1919 Market Street in 1901 Market Street and at Center City West. The group behind the design is the same as the one that designed the CN Tower in Toronto, Canada. The developer of the twin tower project is The Linpro Company, which has only erected one tower that stands out on the skyline.

If both of the towers were built by 1990, they would have given the skyline a modern look, with sharp angled cuts of the dark toned tower bringing a contrast to the west side of the Center City skyline.
The tower was ready to rise to accommodate its anchor tenant, the law firm Blank Rome Comisky & McCauley. The twin towers were canceled and redesigned in 1989 to attract more modern tenants at the time. Unfortunately, the developer did not land any anchor tenants for the project, and it was eventually developed in 2015 into a 335-foot-tall residential tower.
