Bicycle Route Guide Signs and Sharrows

National Standards for Bicycle Route Guide Signs and Markings.



According to MUTCD, we would be proposing Bicycle Route Guide signs. Background must be green, text and border are white (Section 2A.11). Section 9 discusses all approved signs pertaining to bicycles. Minimum sizes are specified in section 9B.3.

Our sign cluster would have:
  • Standard Bike Route - D11-1
  • Destination - D1-1
  • Directional Arrow - M7-1 to M7-7 depending on the arrow type

Underneath this cluster would be the locally designed Best Bicycle Route map depicting all routes, and a link to bikeSB.org.

Shared Lane Pavement Marking a.k.a Sharrows

Shared lane pavement markings (or “sharrows”) are bicycle symbols that are placed in the roadway lane indicating that motorists should expect to see and share the lane with bicycles. Unlike bicycle lanes, they do not designate a particular part of the roadway for the use of bicyclists.

What do sharrows mean for motorists and bicyclists?

Motorists:
• Expect to see bicyclists on the street
• Remember to give bicyclists three feet of space when passing
• Follow the rules of the road as if there were no sharrows

Bicyclists
• Use the sharrow to guide where you ride within the lane
• Remember not to ride too close to parked cars
• Follow the rules of the road as if there were no sharrows


Sharrows are a recent development, currently in testing stages in San Francisco, Seattle, Cincinnati, and other large cities. Sharrows have been recommended for inclusion in the next MUTCD manual, but as of now, there is not an official guideline for their size.
