The first of the famous Roman stone paved roads, the Appian Way, was built in 312 BC, during the Roman Republic, long before Rome had emperors. The Romans built their roads over many centuries and their construction was commissioned by many different men. The emperors were not responsible for building roads. Originally the officer of state responsible for building roads was the censor. When the empire grew too big for one man to be responsible for the building of roads in such a large empire, the responsibility was handed over to the provincial governors. In Italy, a special commission was instituted for this purpose.
It's that one city, with the roads and the buildings.(If you're going to ask us about a state, it helps to be specific as to which state.)
He started a series of campaigns to conquest the territories nearby, but he stopped wars when he converted to Buddhism. He made Buddhism a state religion and sent out missionaries to Syria and Ceylon to spread the new faith. He paved roads for tourists to roam the country. He also wrote edicts on large stone pillars and placed them throughout the land.

1) The Latin name for road was via (plural viae) 2) In the Roman Empire there were 400,000 km/250,000 miles of roads; of these, 80,000 km/50,300 miles were paved. 29 paved roads radiated from Rome. 3) The purpose of the paved roads was military. It speeded up the movement of troops and made their journey easier. It also made the transport of supplies of troops at the front or stationed in garrisons more efficient as they could be moved in larger quantities and faster. They were flanked by a drainage ditch. 4) The first paved road was the famous Appian way built in 312 BC by Appius Claudius Ceacus, the censor of that year, to speed up the movement of troops to the front of the Second Samnite War. At first it reached Capua (north of Naples) and then was extended to Benevento (southeast of Naples). Finally, it was extended to Apulia. 5) The romans liked to build the roads as straight as possible. This sometimes led to tracts which were so steep that they were impractical for trade. Later, they build alternative routes in these spots to make traffic more manageable 6) The roads were named after the man who commissioned its construction 7) A via terrena was an unpaved 'dirt road' of levelled earth, a via glareata had a gravel surface; a via munita was built with rectangular blocks of stone or polygonal blocks of lava. There were also viae rusticate (secondary rural roads) which were unpaved or gravelled. 8) The Roman state built the roads. The provincial governments were responsible for maintenance. Private citizens with an interest in the roads were asked to contribute to maintenance. There were also private roads built by landowners on their lands. These were viae privatae. 9) At Terracina (south of Rome) the Romans cut the bottom of a hill to make space for the Appian way to pass between the hill and the coast. In Romania part of a road is half cut into the rock of a hillside. The Romans also dug tunnels and built bridges. 10) The roads had mile stones. The word mile comes from milia passuum, 1,000 steps. A Roman mile was 1,480 metres/4,841 feet. Milestones were usually round columns 1,5 metres/5 feet high of a base 60 cm/2feet high and a diameter of 50cm/20 inches. The number of the mile of that road was inscribed on it.
Texas has the most paved roads of any US state.
Texas has the most miles of paved roads, i believe it's somewhere around 250,000 miles of paved roads
New Jersey has the most paved roads for its square miles relative to other states in the United States. It is a smaller state with a high population density and extensive road network.
According to NCDOT, they MAINTAIN about 80,000 miles of highways, second, only to Texas. That, of course, doesn't include all paved roads such as some that are in subdivisions maintained by HOAs, municipalities, schools, private streets, etc... They also maintain 12,712 bridges which ranks them #13.
There is usually a sign welcoming you to whatever state you are entering. There is often a visitors center located just inside the state line. The roads of one state may be of a different material (concrete or asphalt) than the other. Even if the roads are of the same material they most likely will have been paved at different times so one will be newer than the other.
Volume
If it's a state/county/city/township/etc. road, then no. The same laws which apply to paved roads apply to those. If it's a private road on private property, and you have permission from the landowner to be on that road, then, by all means, go for it.
Gas....durh!!
Texas produces the greatest amount of helium for any US state, because one large gas field in Texas happens to have natural gas with a relatively large concentration of helium.
No the roads are made out of asphalt.
Florida
Roads facilitated communication between the various parts of the vast Roman Empire. This facilitated general travel, the transport for goods for trade and the journeys of officials and state messengers to the provinces of the empire. About 20% of the enormous road network of the Roman Empire were the famous stone-paved roads. These had military purposes. They speeded up the movement of troops and made the transport of supplies to the solders stationed in garrisons or at the front of wars easier.
