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.
Geneva, Ohio
Three major routes pass through (or near) Geneva. Interstate 90, the northernmost east-west and coast-to-coast interstate, passes roughly two miles south of the city. There, a full-access interchange (exit 218) intersects Route 534, which passes through Geneva and terminates north of the city. Route 534 intersects Route 20, the longest road in the United States, in downtown Geneva.
