Due to inclement weather, the Capitol Visitor Center is closed today, March 5, and there will be no tours of the Capitol.
Post roads, so called because mail was carried over them, date to colonial times. They were the major land routes linking towns. So vital were these links that both houses of Congress established a Committee on Post Offices and Post Roads as one of their first standing committees. As mail was the only means of long-distance communication until the invention of the telegraph in the 1840s, the speed of mail delivery affected every citizen.
