Though the new rainbow crosswalk may look great, I believe that it violates the MUTCD rules concerning what colors can be used in road markings. See section 3A.04.
Also, is the paint retroreflective to be visible during the night?
Oh and section 3B.17 of the MUTCD states that when crosswalk lines are used, they shall consist of solid white lines that mark the crosswalk.
I'm not sure why this wasn't checked before we made this into such a public spectacle. The idea is great but the laws are the laws, especially on a state highway, I would think.
