Overhead Sign Structures

LKB provided design services for the replacement or repair of thirty-four overhead span and cantilever sign structures located on various County roads. Twenty-two sign structures were replaced, seven were either replaced or rehabilitated, four were removed and replaced with ground mounted signs and one was removed/eliminated. The preliminary design included field inspection, non-destructive testing, survey and borings at the locations of the sign structures to be replaced. A report was prepared documenting the inspection findings, presenting alternatives and recommendations along with preliminary estimated construction costs. The final design included sizing and layout of new sign panels, new sign structures and foundations and guiderail. Work zone traffic control plans were developed for each of the sign locations. Engineering support services and inspection services were provided during construction.
