The Kentucky and Ohio Departments of Transportation announced that toll revenue would be required to fund the design and construction of a new Brent Spence Bridge. Current estimates place the cost of a new bridge at $3.57 billion.  The current Brent Spence Bridge is a double-decker cantilever truss bride that crosses the Ohio River.  It allows residents of Northern Kentucky to commute to Cincinnati, Ohio and vice versa.  The bridge was opened in 1963 and was designed to carry 85,000 vehicles per day.  As of 2007, 155,000 cars cross the bridge each day, and about 65% of the cars travel from Kentucky to Ohio.  In 2011, large pieces of concrete fell from the upper deck of the bridge onto the lower level, and the bridge was closed down for a day to repair the damage.  While it currently is considered to be structurally safe, many residents of Ohio and Kentucky have lost faith in the functionality of the original bridge.  As a result, the two states departments of transportation are currently studying the bridge to determine if it will be better to replace or rehabilitate the Brent Spence Bridge.
