On May 7, 1975, one of the main girders of the Lafayette Street Bridge over the Mississippi River in St. Paul, Minnesota, was discovered to be cracked.
Subsequently, on May 18, 1975, Dr. J. W. Fisher visited the site for a visual examination of the cracked girder. An agreement was made with the Department of Highways to investigate the cracked girder in order to ascertain the causes of the cracking and provide recommendations for corrective action-as may be deemed necessary for other details that may need attention.
