U.S. Route 20
U.S. Highway 20 (US 20) is an east–west United States highway that stretches from the Pacific Northwest all the way to New England. The "0" in its route number indicates that US 20 is a coast-to-coast route. Spanning , it is the longest road in the United States, and particularly from Newport, Oregon to Boston, Massachusetts, the route is roughly parallel to that of the newer Interstate 90 (I-90), which is in turn the longest Interstate Highway in the U.S. There is a discontinuity in the official designation of US 20 through Yellowstone National Park, with unnumbered roads used to traverse the park.
Arkansas Highway System
Another convention in 1907 formed road districts, but this did not help the situation either. Although the need for improvement was obvious, the citizens had trouble finding funding for their goals. In December 1913, Arkansas formed the "Dollarway", which was the name of a concrete road with asphalt concrete topping. It was opened near Pine Bluff. By 1914, a segment of was opened, the longest paved stretch in the United States. Today, the route is mostly covered by Highway 365, although some original concrete segments are still visible, and the Dollarway Road portion has been listed on the National Register of Historic Places.
