abstract="As Oregon's freeway signs had exceeded their life span, a program to upgrade these signs by overlaying them where possible was initiated. As contracts progressed, however, it became apparent that sign replacement was more cost effective. All new guide signs will be constructed of extruded aluminum panels covered with encapsulated lens reflective sheeting and reflector button legend. Problems that were encountered as the project progressed are described.<p />",
