Having driven in many cities in the US I would have to say that Detroit Michigan has some of the worst roads in the country. I drive a lot in the state of Oklahoma. In Tulsa, the roads are really bad and uneven. Potholes there range anywhere from 1' to 6' in diameter and up to 2' deep in some places. Those potholes are just the ones located on paved roads. Some dirt or gravel roads have had up to half of the road missing after a big storm."During the fiscal year 2000-01, 83,613 potholes were repaired." That was from a report given by the city, on the conditions of roads in Tulsa. Those numbers, however, are just an estimate of the potholes that have been reported as repaired according to city maintenance records. There are still more potholes that haven't been reported, fixed, or are on roads that the city isn't responsible for maintaining.

Paved roads are important because it is straight and direct for cars to drive and it is good for the driver because it can take the right direction.
Woodward Avenue may have been the first road paved with CONCRETE in the US. That occurred in 1909. The earliest paved roads in the US date at least to the 1820s. Most US cities had paved roads by the 1880s and 90s. The oldest KNOWN paved road is a 7 1/2 mile route in Egypt, not far from Cairo. It was built 4,600 years ago. The 2nd oldest is in Ur, in Iraq, at least 4,000 years old.
Roads were necessary to the Roman republic for the same reasons that roads are necessary for us -- to get people and things from here to there. When we talk about the famous Roman roads, we are talking about the paved roads, rather than the earlier unpaved roads. The first paved road was the Appian way, which was built in 312 BC to speed up the movement of Roman troops to the front of the Second Samnite War (326-304 BC). The Roman Republic needed paved roads for military purposes. This need started when they expanded into Italy through wars with various Italian peoples. The paved roads also made the transport of supplies to the Roman military bases quicker and easier.
