According to the NBC, what is the minimum width of a street?

The minimum width of a street is determined by various factors, including the type of street, its intended use, and the requirements set out in the National Building Code (NBC) or the local building codes and guidelines. In this context, the correct answer reflects the standard that is often established for street widths to accommodate vehicle traffic, emergency access, and pedestrian movement.

A minimum width of 9 meters allows for essential road functionality, ensuring enough space for vehicles to pass, especially in urban areas where traffic density is higher. It also considers the need for parking lanes or sidewalks, contributing to overall safety and accessibility. Such dimensions support effective traffic management, support the emergency services, and promote walkability in a community.

While answers indicating widths of 6 meters or 7 meters may apply to certain situations, such as residential streets with lower traffic volume, they do not meet the broader standards necessary for accommodating mixed traffic flow and safety considerations in more developed areas. A minimum of 10 meters can be excessive in some contexts, often reserved for major thoroughfares or arterial roads that require enhanced capacity to handle larger volumes of traffic.
