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.
Alberta Highway 40
Two interesting facts about highway 40 are: The segment from roughly Hinton to Grande Prairie is part of the shortest fully paved land route from the USA to the Klondike Gold fields in the Yukon, and if the segments of the Forestry Trunk Road and Highway 40 were connected, the total length would be approximately and it would be the second longest highway in Alberta.
