Source-derived summary

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 like 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.

Route description

Oregon

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.

Editorial summary

The public source identifies “U.S. Route 30” as u.S. Numbered Highway in the United States. This brief keeps that definition visible, then builds a research path around Route, Numbered and Highway.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 292-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1926. Its value is orientation rather than verdict, with Route, Numbered and Highway providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “U.S. Route 30”, the useful work is to connect “u.S. Numbered Highway in the United States” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 21, 2026. The linked authority identifier is Q408993. VIAF identifies the subject as 315527201. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
