Maintenance of Signs and Sign Supports

Highway signs are the means by which the road agency communicates the rules, warnings, guidance and other highway information that drivers need to navigate their roads and streets. This guide, which is an update to the same titled guide published in 1990, is intended to help local agency maintenance workers ensure their agency's signs are maintained to meet the needs of the road user. The guide succinctly covers the following topics: a description of sign types, sign materials and sign supports; sign installation, and the elements of a sign management system including inventory, inspection, preventive maintenance, repair and replacement, and recordkeeping.
