The illustration above depicts a wide elevated structure that dominates,the street and carries six lanes of traffic.
At grade, this urban street serves fast-moving through-traffic with service lanes, central travel lanes, and on-street parking. Motorists, cyclists, and transit operate in traffic with frequent conflicts due to differences in operating speeds.
Medians that carry the structure of the elevated road divide the service lanes from the central lane and block the pedestrian crossing.
A lack of marked pedestrian crossings and long distances make it impossible for pedestrian to cross the street without risking conflicts with moving vehicles.
Large structural elements severely limit visibility.
Narrow sidewalks are filled with obstacles, forcing pedestrians to walk on the street in unsafe conditions.
