US 460 between Georgetown and Frankfort is a heavily traveled, rural, narrow two lane roadway with numerous geometric deficiencies and a high crash rate. A one mile section just west of the Georgetown Bypass paralleled Elkhorn Creek and was one of the worst spots along the route. The existing roadway meandered between Elkhorn Creek and a steep hillside and occasionally flooded. This project involved relocating US 460 both horizontally and vertically while minimizing impacts to homes near the existing route. The project also involved numerous utilities that were located along the existing route.
The Kentucky Transportation Cabinet-District 7 staff had started the preliminary design for the project. Due to workload, they requested that HMB finalize the plans through the Statewide Design contract. HMB worked together with the District staff to determine the best location for the proposed route, then delivered right of way and final construction plans. HMB also participated in a public meeting and had numerous on site meetings with property owners who were concerned about impacts to their property. There were existing rock fences along the route which would be replaced with the construction. The project involved a couple of unique entrances, one to a historic home and another to a high end subdivision that required the design to replicate the existing situation. HMB also worked with the gas company and adjusted the location of a proposed box culvert and entrance grades to minimize the required gas line relocation.
This was a challenging project due to the number of residents living along the existing roadway, the utilities paralleling existing roadway, and the location of Elkhorn Creek. The maintenance of traffic was also critical because of the narrow corridor and limited detours available. The teamwork between HMB and KYTC was instrumental in delivering a successful project solution.
