Define the elements of a Class I, Class II, and Class III two-lane highway.

Question

What will be an ideal response?

Answer 1

Class I. Two-lane highways whose function it is to serve as primary arterials,
daily commuter routes, and links to other state or national highway networks.
Motorists’ expectations are that travel will be at relatively high speeds.
Class II. Two-lane highways whose function it is to serve as access to Class I
highways. They also serve as scenic byways and can be used by motorists for
sightseeing; some are located in rugged terrain. Average trip lengths are shorter
than on Class I highways. The expectation of motorists is that travel speeds will
be lower than for Class I roads.
Class III. Two-lane highways that serve moderately developed areas. They may
be a portion of a Class I or Class II highway passing through a small town or a
recreational area. These segments may be used by local traffic and the number of
unsignalized access points is greater than in rural areas. They may contain longer
segments that pass through spread-out recreational areas with increased roadside
activity and reduced speed limits.
