A contractor for the Kentucky Transportation Cabinet plans to restrict traffic to one lane on the US 68/KY 80 Lake Barkley Bridge at Canton TODAY. The daytime lane restriction starting around 9:30 a.m., CDT, is to allow maintenance work on the existing bridge. Motorists should be alert for one lane traffic with alternating flow controlled by flaggers in this work zone. This daytime lane restriction on the existing US 68/KY 80 Lake Barkley Bridge at Canton is expected to be in place from 9:30 a.m., CDT, to about 4:00 p.m., today. The US 68/KY 80 Cumberland River/Lake Barkley Bridge, also known as the Lawrence Memorial Bridge and the Canton Bridge, carries approximately 3,800 vehicles across Lake Barkley/The Cumberland River in an average day. The bridge is located at US 68 mile point 8.596 in Trigg County and serves as the eastern entrance to Land Between The Lakes National Recreation Area. The bridge is at Cumberland River navigational mile point 63.1. PCL Civil Construction of Denver is the contractor on the new $128.3 million Lake Barkley Bridge immediately downstream from the existing structure. The new Lake Barkley Bridge is expected to be open to traffic by October 2017. It will be of a basket handle arch design to match the New Eggners Ferry Bridge over Kentucky Lake under construction at Aurora.
