NORWALK - It was a dangerous morning on I-95 in Norwalk, where four separate accidents on the same one-mile stretch of the interstate sent seven people to the hospital. The four serious accidents happened within a three-hour period of time. Police say seven people were taken to the hospital, some with life-threatening injuries, after Norwalk and Westport firefighters cut them out of their vehicles. Authorities say it's very unusual to see this many accidents back-to-back in such a short period of time.
