Friday, Aug. 1, is the one-year anniversary of collapse of the Interstate 35 bridge in Minneapolis. Thirteen people, including one truck driver, were killed in the incident.
In addition to the deaths, about a hundred other people were injured when the structure gave way just after 6 p.m. on Aug. 1, 2007.
Although faulty steel gusset plates were cited as a possible contributor to the collapse, federal investigators still have not yet declared what they think went wrong.
Memorial observances were planned for Friday afternoon in Minneapolis, including performances by gospel singers and bagpipers.
Meanwhile, the new $234 million bridge is expected to open ahead of schedule this fall, which will earn the construction company $1 million per day for every day by which it beats the Dec. 24 deadline.
