 Large sections of the various routes are still called the "King's Highway" and "Boston Post Road".Much of the Post Road is now U.S. Route 1, U.S. Route 5, and U.S. Route 20.Mileposts were measured from the intersection of Broadway and Wall Street in New York (one block west of Federal Hall) and from the old Boston city-line on Washington Street, near the present-day Massachusetts Turnpike.
