24 in by 24 in (610 mm by 610 mm) California-style U.S. Route shield, made to the specifications of the 2002 edition of Standard Highway Signs with 10 in (250 mm) numerals. Uses the Roadgeek fonts. (United States law does not permit the copyrighting of typeface designs, and the fonts are meant to be copies of a U.S. Government-produced work anyway.)
