Workers install a new sign at the Main Gate at Arnold Air Force Base, Tenn., on Oct. 22, 2020. The new sign, located alongside Wattendorf Highway before entering the base, was necessary after an accident occurred in February 2020, in which a car ran off the roadway and collided with the previous sign. The project was completed by the Simplified Acquisition Base Engineering Requirements (SABER) contractor, SDVE, LLC. (U.S. Air Force photos by Deidre Moon)
