highway-signage

Interstate is a sans-serif designed by Tobias Frere-Jones at Font Bureau, inspired by the lettering on U.S. highway signs (FHWA Series). Released in 1993, it translates the clarity and confidence of American road signage into a versatile typeface for print and screen.

Design Characteristics

Interstate inherits the wide proportions, open counters, and clear construction of highway lettering while refining it for professional typography. Its utilitarian DNA gives it an unmistakable American character — confident without being aggressive, authoritative without being formal.
