The innovative and experimental green bike lanes that have been appearing in cities like Portland, Salt Lake City, New York City, and Long Beach are now officially approved for use. On April 18, the Federal Highway Administration approved "the optional use of green colored pavement in marked bicycle lanes and in extensions of bicycle lanes through intersections and other traffic conflict areas." This approval gives the green light to traffic engineers and planners across the country who previously wouldn't use the paint because it wasn't officially approved. This news, along with Janette Sadik-Khan's announcement of the NACTO Urban Bikeway Design Guide at the National Bike Summit, paves the way for dramatic improvements in national standards for bike infrastructure, signage and markings.
