In accordance with Executive Order 11593 and other applicable federal laws and regulations a Phase I archaeological survey was conducted in September 1994 of approximately 8.1 ha (20.2 acres) for three proposed bridge replacement areas on the Fort Knox Military Reservation, Hardin and Meade Counties, Kentucky. The survey resulted in the recording of two archaeological sites, 15Hd497 and 15Md382, and revisiting of two previously recorded prehistoric sites, 15Hd170 and 15Hd209. None of the sites is eligible for the National Register, due to previous disturbance. No additional archaeological work is recommended for 15Hd17O, 15Hd209, 15Hd497, or 15Md382. Due to the potential for deeply buried cultural deposits, it is recommended that any machine excavations on the left bank of Mill Creek at Bridge 10, and on the right bank of Otter Creek north of the existing bridge be monitored by a qualified professional archaeologist. Alternatively, test trenches could be excavated in these areas in advance of the bridge construction. The other portions of the Bridge 7, 10, and 12 project areas do not require monitoring of construction excavations.
