During major traffic-disrupting events (a marathon, for example) temporary pedestrian bridges should be constructed and placed over major, important, or critical automobile traffic choke points. For example, marathon runners would be required to run up and down over temporary bridges (maybe arched bridges) so that normal automotive traffic patterns would not be excessively disrupted.

Also, during such large planned or even unplanned (if possible) traffic disruption events, police officers and traffic enforcement/guiding personnel should be required to give out free copies of maps to affected motorists and others who ask. These maps should map out the entire area and delineate as specifically as possible the major streets (and other areas) affected as all road blockages or closures, detour routes, and the schedules (if available) of the disruptive events.
