U.S. Route 30
U.S. Route 30 or U.S. Highway 30 (US 30) is an east–west main route of the United States Numbered Highway System, with the highway traveling across the Northern U.S. With a length of 3,112 miles (5,008 km), it is the third-longest U.S. Highway, after US 20 and US 6. The western end of the highway is at US 101 in Astoria, Oregon; the eastern end is at Virginia Avenue, Absecon Boulevard, and Adriatic Avenue in Atlantic City, New Jersey. The "0" as the last digit in the number indicates that it is a coast-to-coast route and a major east–west route. Despite long stretches of parallel and concurrent Interstate Highways, it has not been decommissioned unlike other long-haul routes such as US 66. It is also the only U.S. Highway that has always been coast-to-coast since the beginning of U.S. Numbered Highway System.
US 20 and US 30 break the general U.S. Highway numbering rules in Oregon, since US 20 actually starts south of US 30 in Newport, running through the middle of Oregon, while US 30 runs parallel to the north of the state (the Columbia River and Interstate 84, or I-84). The two run concurrently and continue in the correct positioning near Caldwell, Idaho. This situation is because US 20 was not a planned coast-to-coast route while US 30 was.
Much of the historic Lincoln Highway, the first road across the U.S. (from New York City to San Francisco), became part of US 30; it is still known by that name in many areas.
The western terminus of US 30 is at an intersection with US 101 at the southern end of the Astoria–Megler Bridge in downtown Astoria, Oregon, approximately five miles (8.0 km) from the Pacific Ocean. It heads east to Portland, where it uses a short section of freeway built for the canceled I-505. From there, it heads around the north side of downtown on I-405 and I-5 to reach I-84. Most of the rest of the route is concurrent with I‑84, with only about 70 miles (110 km), under a fifth of its remaining length, off the freeway, mainly on old alignments.
Upon entering Idaho, US 30 runs along its old surface route through Fruitland and New Plymouth before joining I‑84. It leaves at Bliss and soon crosses the Snake River, running south of it through Twin Falls and Burley before crossing it again and rejoining I‑84. At the split with I-86, US 30 continues east with I‑86 almost to its end at Pocatello. US 30 cuts southeast through downtown Pocatello to I-15, where it heads south to McCammon. There, it exits and heads east and southeast into Wyoming, not paralleling an Interstate Highway for the first time since Portland.
In Wyoming, US 30 heads southeast through Kemmerer to Granger, where it joins I-80 across the southern part of the state. It is also here that it joins the historic Lincoln Highway. As in the previous two states, US 30 remains with the Interstate highway for most of its path, only leaving for the old route in the following places:
Unlike the three states to the west, Nebraska keeps US 30 completely separate from its parallel Interstates (I-80 in this case). From the state line to Grand Island, US 30 closely parallels I‑80. East of Grand Island, US 30 diverges from I‑80 and runs northeast toward Columbus on a highway parallel to the Platte River. At Columbus, it turns east toward Schuyler and Fremont and crosses the Missouri River into Iowa east of Blair.
US 30 crosses Iowa from west to east approximately 20 miles (32 km) north of I-80. Between Missouri Valley and Denison, US 30 runs in a southwest–northeast direction. The majority of US 30 east of Ames and west of the Mount Vernon–Cedar Rapids area (138 miles [222 km]) is a rural four-lane divided highway. A portion of the highway in Tama County is being upgraded to a divided highway. US 30 between Mount Vernon and Dewitt is a two–lane highway. It crosses the Mississippi River into Illinois on the Gateway Bridge at Clinton.
