The Kentucky Transportation Cabinet plans a work zone restriction on the U.S. 68/KY 80 Lake Barkley Bridge at Canton in Trigg County starting Tuesday to allow a detailed inspection of the bridge structure.
District 1 spokesman Keith Todd says one lane will remain open in each direction during the inspection process. He notes there will be an 8-foot load width restriction for westbound traffic due to the use of an under-bridge inspection vehicle on the lanes.
The trail walkway on the south side of the bridge will be closed to allow inspectors to climb the bridge structure.
Weather permitting, the inspection team anticipates being on the bridge from around 8 a.m. to about 4 p.m. each day from Tuesday through Friday. Todd says if additional time is needed for the inspection the team plans to return on Monday, August 9.
All traffic will move to the left-hand or passing lane with the work zone to remain up overnight until the inspection is complete due to equipment being on the bridge deck.
Todd says the detailed safety inspection is conducted every two years on all Kentucky bridges with long-span river and lake bridges getting an additional annual walk-through inspection. The Kentucky Transportation Cabinet is responsible for inspecting bridges on all public roadways in the commonwealth.
Approximately 5,000 vehicles travel across the U.S. 68/KY 80 Cumberland River/Lake Barkley Bridge, also known as the Henry Lawrence Memorial Bridge and Canton Bridge, in an average day.
The new $128 million bridge that features a basket handle arch design that matches the design of the U.S. 68 Eggners Ferry Bridge at Aurora opened to traffic on February 12, 2018.
