Lake Barkley Bridge carries US 68 and KY 80 across Lake Barkley near Cadiz in Trigg County, Kentucky. It is officially named after Henry Lawrence.
The Lake Barkley Bridge opened to traffic in 1932.4 In 1963, the bridge was closed to traffic and the crossing was elongated and raised as part of the Lake Barkley project. During the closure, a ferry was established.
The bridge carries 2,800 vehicles per day.2
As part of the four-lane upgrades of US 68 and KY 80 in southern Kentucky, the Lake Barkley Bridge was slated for replacement with a four-lane crossing. The bridge selection process began in mid-2007, which included arch, girder, truss and cable-stay bridge types.3 On July 14, 2009, Governor Beshear unveiled the design of the replacement, a tied arch span that would be unique to the state.1 The new 550-foot, four-lane bridge design included 11-foot lanes, 4-foot shoulders and a separate 8-foot sidewalk and bike path.
The estimated cost of the design and construction of the new bridge is $178 million.1 Construction is expected to begin in 2011 and be completed by the fourth quarter of 2017.
The four-lane alignment through Land Between the Lakes, which is situated between Kentucky Lake and Lake Berkley, was completed in November 2010 after being under construction for three years.
