A Kentucky Transportation Cabinet geotechnical drilling crew is working on preparations for construction of new bridges to cross Kentucky Lake on U.S. 68-80.
The drilling work must be done near the Eggners Ferry Bridge site at the Trigg-Marshall County line to determine where exactly bridge piers can safely be built. Officials say they are taking a sample of rock beneath the lake bed every few feet to provide a profile of sub-surface conditions.
Two new brides will be built at the site, with work on the approaches to begin as soon as next year. Work on the actual bridges may not begin until 2014 and the project should take about four years.
Construction of bridges over Barkley is expected to begin in the next few years. The projects have been sought after for several years, especially after a cargo vessel knocked out a span of the Eggners Ferry Bridge in January, which closed it until the Memorial Day weekend.
A motor vessel is at the drilling sight 24 hours a day to assist any barge traffic in successfully navigating under the bridge while work is ongoing.
