In the 2009 Manual on Uniform Traffic Control Devices (MUTCD), the Federal Highway Administration (FHWA) updated the standard concerning the sign lettering style for names of places, streets and highways (§2D.05). Formerly, names on signs could either use all uppercase lettering or only capitalize the first letter. Recommendations from the 2009 edition of the MUTCD eliminated the option of using only uppercase lettering because studies indicate that mixed-case lettering is easier to read and react.State and local transportation agencies are required to implement the new lettering style as they install new signs or replace existing signs. In July 2014, Arlington began using the new lettering style on street name signs as part of the Transportation Engineering & Operations (TE&O) Bureau routine maintenance initiatives. As federally mandated, street name replacement in Arlington is an ongoing effort until all signs have been upgraded or until the standard lettering requirement is revised.If your street name sign is damaged, faded, or broken and needs replacement, submit your request via the Report a Problem Application.
