County and Arterial Roads

County roads

Smaller, narrower, and sometimes not paved, county roads extend to the interior of regions in the United States, and are well-known and better traveled by local people. They often are a smaller sign, a blue shield with the county name at the top and a number.


Arterials are roadways important for moving traffic from outer, less traveled and more rural areas, into heavier trafficked areas. When thinking of these types of roadways, imagine the circulatory system of the human body: You can trace capillaries to veins to larger veins, then smaller arteries and larger arteries before it reaches the heart (a city, let’s say). This is designed to be a gradual process avoiding as many bottlenecks, which are jams of many vehicles at a critical junction point where two-or-more roads meet.

In cities, arterials link a downtown or central business area with outer residential or business areas and extend out of the city into towns. They also join traffic to interstates and freeways.

Whereas pedestrians cannot travel on interstates and freeways, they ARE allowed to cross at carefully controlled intersections on arterials. Main arterials do not allow parking, because their function is to direct traffic along to larger highways and the interstate system
