I would like to find information concerning centerline painting along Fort Washington Ave between Limekiln and Welsh. Historical arial photos only show centerlines present after 2005. Can someone from the township please provide a township record relating to / defining this change or requirement for these lines? Note: Photo example of 2005 showing sample section between Limekiln and Terrrace dated 2005 showing no centerline markings.
