Good points all.

To DCCommuter: As long as you are aware that additional proof may be required in order to legally take the lane in a over 11' lane in DC.

To Bek: All good points but what do you see the advantage of a centered positioned sharrow over a BMUFL sign (Bikes May Use Full Lane) or the standard share the road signs?

For those of you who want to officially comment on Sharrows I'll direct you here: http://www.baltimorespokes.org/artic...80330163659675

And getting back to my problem in more general terms what would be the best treatment for two travel lanes (same direction) with 22' of ROW with the right lane used as off peak parking and the speed limit is 35mph (major arterial.)
