This report documents the findings from the investigation of pavement edge drains and headwall conditions on six Watterson Expressway Projects in Jefferson County. These projects include the Newburg Road Interchange, Bardstown Road Interchange, Taylorsville Road Interchange, Breckinridge Road Interchange, l-64 1nterchange, and Shelbyville Road Interchange. The study was initiated due to an on-site inspection by Federal Highway Administration, Kentucky Transportation Center, and District 5 personnel who indicated several of the outlet pipes were clogged or collapsed. It was suggested by Federal Highway Administration personnel that a mini pipeline inspection camera be used to verify the conditions of the outlet pipes and mainlines. Findings from this study indicated that approximately 49 percent of the combined 467 pavement edge and cross drains from all six projects were less than 50 percent open.
