Reported on April 23, 2011 as ticket # 96819, which is Archived & cannot be reopened. See details here: http://www.seeclickfix.com/issues/96819 Reopening.
Bicyclists when riding eastbound on Mt Vernon crossing after Ashford-Dunwoody, the "extended curb" comes to a point at the end. This is a very dangerous point for bicyclists, as they must immediately do a lane change and merge to the right lane. Painting a "bike lane" marker with bicycle symbols and directions will indicate to drivers to allow bicyclist to merge into the right lane. This is a safety improvement.
