There are 3 notes in the Infobox. MOS:INFOBOX says, inter alia, the purpose of an infobox: to summarize (and not supplant) key facts that appear in the article. Consider if this material in the infobox links ought be in the article itself. See WP:INFOBOXREF.
There are two archived discussions on this matter, references and External links in the Infobox. References should be in the body of the article.
The general rule is that all facts in the InfoBox should be repeated in the article body, and the reference/cite should appear at that body location, not in the InfoBox. In the rare situation where a fact only appears in the InfoBox (and it is "likely to be challenged" per WP:V) then a citation should be in the InfoBox. For example, Albert Einstein has two footnotes in the infoBox. But, in most well-written articles, all facts in the InfoBox will be elaborated upon in the body.

The website link in the foot of the Infobox is a dead link. Archived version
Reference 2, 3 are dead links
References 6, 7, 8, 9, 10, 11, 12 are dead links. Like Reference 2 and 3, these Google news links are not working. These are all from the Milwaukee Journal. Perhaps they can be found on one or another Archive site? Or on Newspapers.com ?
This sentence is overlinked: Along with bank officials, mayor Henry Maier, county executive John Doyne, and Wisconsin governor Patrick Lucey attended the ceremony.
We don't need links for mayor, county executive, nor the List of Governors of Wisconsin. Drop. Readers of the English language are cognisant of these terms.
Ditto First Wisconsin Center; we don't need links to monopoly, litigation, antitrust, hearsay, nor Dallas in the next paragraph.
Reference 15 does not follow MOS for the Milwaukee Sentinel.
In the section Firstar Center we may drop the link to economic development.
In the next paragraph we may drop the link to Cincinnati.
In the U.S. Bank Center we may drop the link to parking garage. We may also lose precast concrete and parking space. In the next paragraph, the final link to Chicago may be dropped.
In the Architecture section, the text 42-story links to the storey article. This may be dropped. We may also drop the link to Melbourne.
In the section Peregrine falcons, we do not need a link to World War II. Remainder of the references and links are suitable.
Editing of all links to Google news is mandated. Suggestions are given above.
Common sense needs to be applied to necessary links; many are superfluous and assume ignorance instead of common sense. Nonetheless, the prose is good and NPOV is preserved.
