U.S. Route 87
U.S. Numbered Highway in the United States
U.S. Highway 87 (US 87) is a north–south United States highway (though it is signed east–west in New Mexico) that runs for 2,005 miles (3,227 km) from northern Montana to southern Texas, making it the longest north–south road to not have a "1" in its number and the third longest north–south road in the country, behind U.S. 41 and U.S. 1. Most of the portion from Billings, Montana to Raton, New Mexico is co-signed along Interstates 90 and 25. It is also co-signed along the majority of I-27 in Texas and future plans call for the interstate to be extended along the US 87 corridor. As of 2004, the highway's northern terminus is in Havre, Montana, at US 2 and its southern terminus is in Port Lavaca, Texas, at SH 238.
Route description
Texas
In Texas, US 87 is a north–south highway that begins near the Gulf Coast in Port Lavaca, Texas, and heads north through San Antonio, Lubbock, Amarillo, and Dalhart to the New Mexico state line near Texline.
New Mexico
US 87 continues in a northwesterly direction in New Mexico and is signed by NMDOT primarily as an east–west route. It merges with US-64 (and thus the Santa Fe Trail National Scenic Byway) in Clayton, shortly after entering New Mexico. It continues to the northwest until Des Moines, when it takes a more westerly approach to Raton. In Raton, it separates from US 64 and merges with Interstate 25 and US 85, with which it remains concurrent through Raton Pass and into Colorado, though it is unsigned on much of the concurrency.
Colorado
US 87 remains concurrent with I-25 throughout the state of Colorado, which is a rare occurrence for a US highway to have a concurrency with an Interstate in its entirety within state boundaries.
“U.S. Route 87” enters the record as u.S. Numbered Highway in the United States. Crown Archives preserves that source wording while asking what Route, Numbered and Highway can confirm, complicate or overturn.
Why this record matters
“U.S. Route 87” is worth following because a concise public description often conceals a longer documentary argument. Here, Route, Numbered and Highway provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q410730. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2004.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
