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.
Lincoln Highway (Omaha)
The Lincoln Highway in Omaha, Nebraska, runs east–west from near North 183rd Street and West Dodge Road in Omaha, Nebraska, towards North 192nd Street outside of Elkhorn. This section of the Lincoln Highway, one of only that were paved with brick in Nebraska, is one of the most well-preserved in the country. The roadway was listed on the National Register of Historic Places in 1984. The Lincoln Highway was the first road across the United States, traversing coast-to-coast from Times Square in New York City to Lincoln Park in San Francisco, California.
