What additional no parking zone is prohibited?

Parking on a bridge or underpass is prohibited for key safety and structural reasons. Bridges and underpasses are critical parts of road infrastructure designed to facilitate traffic flow safely without obstruction. When vehicles are parked in these areas, it can create hazards for both moving traffic and parked vehicles. For example, a parked vehicle may block the view of oncoming traffic, creating potential collisions, or impede the path of emergency vehicles that need to pass through. Additionally, parking structures like these are more susceptible to creating traffic jams and hazards due to their confined spaces and limited room for maneuvering. By prohibiting parking in these areas, authorities are ensuring that roads remain clear for safe passage and that critical infrastructure is not compromised.

The other options, while they may have restrictions, do not carry the same level of immediate danger or structural integrity concerns as parking on a bridge or underpass.
