After decades of use and months of planning, it took just 4 seconds for the Fort Steuben Bridge to come down. The Joseph B. Fay Co. -- the same company that worked to bring down the 118-year-old Bridgeport Bridge last September -- worked with Controlled Demolition Inc. to execute this much larger job. Crews used 490 shaped charges and 153 pounds of explosives that had been strategically mounted in 136 locations all over the bridge. 
Water traffic will be suspended for about a day because the U.S. Coast Guard required the river be back open within 24 hours. A Pittsburgh-based company will use heavy machinery to load pieces of the bridge onto several barges. Some of the pieces are expected to weigh as much as 120,000 pounds.
