United States Road Classification
|Part of WikiProject United States.|
This list is the base for US road classification. It is based off the US administative system already in place with minor modifications for trunk class and urban areas. Any state, or city clarifications should be noted on their apropriate page.
- Interstate Highways
- A Divided highway that is entirely grade separated.
- Short sections of grade separated, divided highway that are not connected to a regional network of grade separated, divided highways should probably have the same classification as the highway they are part of. This may differ from the classification implied by AASHTO or FHWA (AASHTO/FHWA standards are only able to imply the classifications for OSM roads as they do not have any authority over OSM).
