The starting date for a break repair project on KY 52 (Richmond Road) at mile point 3.9, just east of KY 594 (Pea Ridge Road), has been moved up. Originally scheduled to begin on Aug. 30, the work will now commence on Wednesday, August 25. However, closure of the eastbound lane and traffic control set up will take place the night before – on August 24 at 7:30 pm
A soil nail system will be used to correct a persistent break. This repair is expected to take approximately four weeks. While the work is ongoing, the eastbound lane of KY 52 will be closed, and eastbound traffic directed into the westbound passing lane via barrels and cones. The speed limit will be reduced from 55 mph to 45 mph, with portable radar panels in use to advise drivers of their speed. While the project is underway, the western entrance to Rogers Lane will be closed. Drivers needing access to or from that county route can use the eastern entrance. While work will only take place between approximately 7 a.m. and 6 p.m., the lane closures and reduced speed limit will be effect 24 hours a day for the duration of the project.
Soil nail repairs have proven to be effective in places where traditional steel drilling may not be as effective. A soil nail wall includes a drainage system so that water which otherwise would accumulate underneath the road surface will flow away from the highway.
Soil nail walls are constructed by inserting steel reinforcement bars (rebar) into the soil, anchoring them into the soil strata. The soil nails and drainage pipes are grouted into place and mesh is attached to the bar ends to hold the slope face in position. The surface is then covered with concrete.
