How Wide Are Highways?

[DelCamille]

Lane width is 3.75 meters and 3.5 meters. Here is the relevant introduction: Highways: Highways are a type of road classified by technical grade, ranking above Class I, Class II, Class III, Class IV, and substandard roads. Highways intersect with national or provincial roads in the hierarchical classification of the road network, meaning highways are part of national or provincial roads within the network. Highway Network: The highway network not only includes routes that meet the technical grade standards for highways but also encompasses some express routes that serve high-speed transportation functions. These are mostly closed Class I roads, often integrated with other highways for toll collection.
