The U.S. Bicycle Route sign can be found in the Federal Highway Administration’s (FHWA) Manual on Uniform Traffic Control Devices (MUTCD).
U.S. Bike Routes are not required to be signed; however, state Departments of Transportation (DOT) and local road agencies along with state partners are encouraged to provide signs and markings for the routes.
The black on white version (click image to enlarge) of the M1-9 U.S. Bicycle Route sign is the one currently in the 2009 edition of the MUTCD. The earlier version of the sign, which is still found on many roads across the U.S., has the number on top, bicycle on the bottom.
The white on green version (click image to enlarge) was designed and endorsed by the National Committee on Uniform Traffic Control Devices (NCUTCD) to replace the older black and white version. In May 2012, FHWA gave interim approval for the optional use of the alternative design for the U.S. Bicycle Route (M1-9) sign. So, a state that is ready to sign U.S. Bike Routes may use the current black and white U.S. Bike Route sign or can use the newly approved green and white version.
Several states are currently signing U.S. Bicycle Routes. Sample sign plans are available upon request. Please contact firstname.lastname@example.org.
