On Tuesday the obsolete Fort Steuben Bridge was destroyed in a spectacular controlled demolition that required 153 pounds of explosives. The Ohio Department of Transportation has released a very loud(!) video of the demolition—be sure to catch the slow motion replay at the 0:25 mark. The bridge was built in 1928 and spanned the Ohio River, connecting Steubenville, Ohio to Weirton, West Virginia. It was declared structurally unsound and closed to traffic in 2009.
