U.S. Highway 87 (US 87) is a north–southUnited States highway (though it is signed east–west inNew Mexico) that runs for 2,005 miles (3,227 km) from northernMontana to southernTexas, 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, behindU.S. 41 andU.S. 1. Most of the portion fromBillings, Montana toRaton, New Mexico is co-signed alongInterstates 90 and25. It is also co-signed along the majority ofI-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 inHavre, Montana, atUS 2 and its southern terminus is inPort Lavaca, Texas, atSH 238.
In Texas, US 87 is a north–south highway that begins near theGulf Coast inPort Lavaca, Texas, and heads north throughSan Antonio,Lubbock,Amarillo, andDalhart to theNew Mexico border nearTexline.
US 87 continues in a northwesterly direction inNew Mexico and is signed byNMDOT primarily as an east–west route. It merges withUS-64 (and thus theSanta Fe Trail National Scenic Byway) inClayton, shortly after entering New Mexico. It continues to the northwest untilDes Moines, when it takes a more westerly approach toRaton. In Raton, it separates from US 64 and merges withInterstate 25 andUS 85, with which it remains concurrent throughRaton Pass and into Colorado, though it is unsigned on much of the concurrency.
US 87 remains concurrent withI-25 throughout the state ofColorado, which is a rare occurrence for a US highway to have a concurrency with an Interstate in its entirety within state boundaries. It is unsigned through the entire state.
US 87 remains concurrent with Interstate 25 northward until exit 160 east of Glenrock where it joinsUS Route 20/US Route 26 from Glenrock to Casper. In Casper it splits from US-20/26 and rejoins I-25 at exit 186. It then remains concurrent with Interstate 25 northward until its terminus withInterstate 90. It then follows I-90 west to exit 44 where it runs up to Sheridan. A portion of US-87 has been washed out for several years along this stretch and "temporary" detour signs are posted directing US-87 traffic alongWyoming Highway 193 through Story. In Sheridan US-87 rejoins Interstate 90 into Montana.
US 87 remains concurrent with Interstate 90 westward until Billings, where it breaks off and heads north. BetweenCrow Agency and Billings, US 87 and I-90 are merged withUS 212. It intersects with (and briefly merges with)US 12 inRoundup and continues north with a slight bend to the northwest until, atGrass Range it takes a sharp turn to the west at an intersection withMontana State Highway 200. US 87 remains concurrent with Montana State Highway 200 until Great Falls. InLewistown, it merges withUS 191 and remains heading generally west. Some ten miles (16 km) out of Lewistown, it breaks with US 191 and merges withMontana State Highway 3, heading generally northwest and merging briefly withUS 89 before breaking with all three inGreat Falls. US 87 heads northeast then east toFort Benton and then generally northeast to its terminus withUS 2 about two miles (3.2 km) west ofHavre.

US 87 originally ran northwest out ofGreat Falls, Montana, towards the eastern border ofGlacier National Park. US 87 ran to the Canadian Border at thePiegan Border Crossing. This was changed in 1934, whenUS Route 89 was diverted to US 87's routing to Glacier Park. US 87 ended in Great Falls until circa 1945 when it was extended to its current northern terminus inHavre, Montana.[1]
U.S. Route 185 was formed in 1926 and extended from US 85 inCheyenne north toOrin. It became part of a southern extension and realignment of US 87 in 1936.
On March 15, 2022,a bill was signed by PresidentJoe Biden that added the extension of I-27 from its termini inAmarillo andLubbock, Texas, northward toRaton, New Mexico, and southward toLaredo, Texas, respectively to the Interstate Highway System utilizing the US 87 corridor. The interstate's northern terminus would be atI-25.[2] A bill introduced in 2023 would explicitly designate the extension as I-27 with twoauxiliary routes numbered I-227 and I-327. I-227 is proposed to be routed viaSH 158 fromSterling City to Midland andSH 349 from Midland toLamesa; I-327 would utilize US 287 fromDumas to theOklahoma border.[3][4] However, after legislation passed through the U.S. Senate in August 2023, I-227 and I-327 were respectively redesignated as I-27W and I-27N, with I-27E replacing the proposed I-27 between Sterling City and Lamesa.[5][6]
