1 Many roads, particularly urban interstates, often have a lower posted speed limit than the maximum allowable shown in this table.

2 Limited-access roads are multi-laned roads with restricted access using exit and entrance ramps rather than intersections.

KEY: NA = not applicable.

NOTE: Interstates are divided into urban and rural sections based primarily on population size and population density.
