25 in by 30 in (635 mm by 762 mm) Interstate shield, based off of 1971 Caltrans sign drawing (still in use). 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 Red 187 and Blue 294), converted to RGB by [2]. Do not convert the text to paths, as this file is inteded for use as a template for users wanting to create shields in the Caltrans 1971 specifications.
