U.S. Route 30 ( US 30 ) is an east–west main route of the system of United States Numbered Highways , with the highway traveling across the northern tier of the country. It is the third longest U.S. route, after U.S. Route 20 and U.S. Route 6 . The western end of the highway is at Astoria, Oregon ; the eastern end is in Atlantic City, New Jersey . Despite long stretches of parallel and concurrent Interstate Highways , it has not been decommissioned like other long haul routes such as U.S. Route 66 .
U.S. Highway 30 runs from the Atlantic coast in Atlantic City, New Jersey to the Pacific coast at Astoria, Oregon, a distance of 3073 miles. It is one of the original routes commissioned in 1926, and was the first route to be paved coast to coast, which was accomplished in 1935. A large length of it follows the old Lincoln Highway, and in the west, much of it also follows the Oregon Trail.
