Comerica Bank Tower (formerly Momentum Place, Bank One Center and Chase Center) is a 60-story postmodern skyscraper located at 1717 Main Street in the Main Street District in downtown Dallas, Texas.

[6] Construction began in 1985 and the tower opened in 1987, with MCorp initially leasing 600,000 square feet (56,000 m2) of space after moving from the Mercantile National Bank Building.

At time of completion it was the most legally-contested building on the Dallas skyline due to the economic downturn of the late 1980s and the savings and loan scandal.

[7] Without a lead tenant, the tower was remarketed into fully leasable class AA office space.

[8] In 1997 Crescent Real Estate Equities, in partnership with the financer Trizec Properties, bought the Bank One Center from Cigna and the Teacher Retirement System of Texas for $238 million.

[9] On December 14, 2006, Crescent sold the structure for US$216 million to Los Angeles–based Metropolitan Real Estate Developers.
