A 400-foot segment of the Leo Frigo Bridge over the Fox River in Green Bay, Wis., has developed a "pronounced dip in the concrete deck" and now sags about two feet, according to state highway officials. Officials speculate that the dip was caused by steel pylons that sank into the ground. The four-lane bridge that carries 40,000 vehicles per day has been closed since Wednesday. Experts have been dispatched to examine the cause and determine what repairs are needed.
