Sign for Florida State Road 570 (toll), also known as the Polk Parkway.

24 in by 30 in (600 mm by 750 mm) Florida toll State Road shield, made to the specifications of the sign detail. Uses the Roadgeek 2005 fonts archive copy at the Wayback Machine. (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.) Colors are from [1] (Pantone Green 342), converted to RGB by [2]. The outside border has a width of 1 (1/16 in) and a color of black so it shows up; in reality, signs have no outside border.

Note that the drawing provides little in the way of measurements, but is generally very accurate. The Florida outline is from the sign detail^{[dead link]} for normal State Road shields, which is used according to [3]. The state outline and number positioning is guessed.
