What is the height requirement for a structure utilizing air rights above a carriageway?

The height requirement for a structure utilizing air rights above a carriageway is set at 4.27 meters. This measurement is typically derived from regulations that ensure the safe passage of vehicles and pedestrians beneath the structure while allowing for adequate headroom.

Maintaining this height standard helps to reduce the risk of accidents and enhances accessibility in both urban and suburban environments. Additionally, it aligns with common building codes that dictate how structures should interact with public infrastructure.

This regulation recognizes the importance of sufficient vertical clearance to accommodate various vehicle types and their heights, while also considering emergency response needs and the overall functionality of the transportation network. Other height options listed do not meet this regulatory standard, demonstrating the importance of adhering to established guidelines to ensure safety and compliance in urban planning and development.
