[6] On March 18, 1971, bank officials unveiled the final design as a 42-story, 601-foot (183 m) skyscraper, encompassing a full block fronting on East Wisconsin Avenue.

[3] Designed by James DeStefano of the Chicago office of Skidmore, Owings & Merrill, with Fitzhugh Scott Architects of Milwaukee serving as an associate planner for the project, the name of the tower was announced as the First Wisconsin Center.

[7] Along with bank officials, mayor Henry Maier, county executive John Doyne, and Wisconsin governor Patrick Lucey attended the ceremony.

[8] In July, one worker died and four others were injured when a derrick used in installing a 175-pound (79 kg) aluminum panel broke free and fell 41 floors to the ground.

[13] After remaining under the ownership of First Wisconsin since its opening, in June 1987 it was announced the tower would be purchased for $195 million by the Dallas development company Trammell Crow.

[14] At the time of the announced sale, Trammell Crow unveiled plans to construct a 50-story tower southeast of the First Wisconsin Center in overtaking it as the state's tallest building.

[18] In 1996, a $1.2 million skywalk was constructed over Van Buren Street to connect the tower with the neighboring Lewis Center.

[19] The addition was funded in part by the city of Milwaukee as an economic development project as Firstar had significant operations in both the tower and neighboring Lewis Center.

[20] The following November Star Banc Corporation of Cincinnati announced the re-purchase of the tower into company hands for $200 million at the time of their purchase of Firstar.

[26] The visible trusses at the top of the building near the U.S. Bank sign are also sometimes lit in germane colors to signify events such as holidays.

[3] Structurally, U.S. Bank Center uses a belt truss system engineered by both Graham and Fazlur Rahman Khan.

[27] Using elements similar to those used in one of Khan's prior works (the BHP House, since renamed 140 William Street, in Melbourne, Australia), the three diagonal belt trusses provide for a dramatic contrast with the vertical facade in serving both structural and aesthetic purposes.

[33] The plan was initiated in an effort to reintroduce peregrines within Wisconsin as their whole population in the state were killed off due to the widespread use of DDT in agriculture following World War II.
