What locations are prohibited for parking near elevated structures?

The prohibition of parking on any bridge, viaduct, or within highway ramps is rooted in safety and accessibility considerations. Parking in these areas can obstruct the flow of traffic, create hazards for drivers and pedestrians, and impede emergency response vehicles. Elevated structures such as bridges and viaducts are typically designed to facilitate the smooth movement of vehicles, and allowing parking in these zones would not only increase the risk of collisions but could also lead to significant traffic disruptions.

Moreover, highway ramps serve as vital connectors between different traffic flows, and any parked vehicles can lead to dangerous congestion or block access for service and emergency vehicles. Thus, regulations often dictate that these critical areas remain clear to ensure safe and efficient transport.

Other options may involve restrictions, but they do not carry the same level of risk or urgency associated with elevated traffic structures. While parking within a foot of a structure or on sidewalks adjacent to them can sometimes also be restricted, these rules are typically less stringent compared to the must-keep-clear mandates for bridges and ramps. Similarly, designated parking lots have specific allowances for vehicular parking and are not subject to the same prohibitions as elevated structures.
