Videos of the presentations of the five teams vying to redesign Navy Pier are now posted online, although they are somewhat difficult to find.
To get to them, click on this link, which will take you to the Web site of Navy Pier. Inc., the pier's governing board, and its page about the proposals of the five teams. Then, under the heading of each team, click on “view concepts.” That will direct you to the Web page with videos. Once you get there, you'll have to scroll down to find them.
Pier officials tell me that they're likely to announce a winner in the contest in late February or early March.
