==An actual date would be helpful== 
 "Roman roads (in Latin, viae - singular via) were vital to the maintenance and development of the Roman state, and were built from about 500 BC through the expansion and consolidation of the Roman Republic and the Roman Empire.[1]" This leaves me wanting an actual date, even approximate for when the Romans stopped building these roads. "the expansion and consolidation of the Roman Republic and the Roman Empire" is way too  vague. At least give a century, please, so the lede is more informative.
