The route continues northeast, intersecting several forest roads before bending northwestward. The route intersects several small roads while it runs parallel to a small creek. It crosses over the
History
On October 9, 1922, a road in the general location of MT 87 was added to the Montana State Highway system.[1]: 137 By at least 1924, an auto trail known as the Banff Grand Canyon Road ran along the highway in the general location of MT 87.[7] The next year, the highway had been given a graded dirt surface, and was designated as part of the Great White Way auto trail, as well as the Banff Grand Canyon Road.[8] Between 1925 and 1927, the auto trail designations were removed from the stretch of highway near present-day MT 87.[9] By 1937, the main highway had been shifted north of the location of MT 87, and had been numbered as State Highway 1. A road remained in the location of MT 87, although it was unnumbered. This road had also been extended several miles northward to Lyon.[10]
By 1951, the highway had been reconstructed generally along MT 87's present location, and it had been upgraded to an improved gravel road.[11] In 1959, the road in the location of MT 87 was rapidly improved in order to serve as an alternate routing to US 287. Portions of US 287 around Hebgen Lake collapsed and crumbled as a result of the 1959 Hebgen Lake earthquake. After US 287 was fixed, the highway's importance decreased.[12][13] In 1962, the portions of the highway from the southern terminus to present-day milepost 8.395 were reconstructed along the current location. In 1967, the rest of the highway was reconstructed along the present location.[1]: 155 By 1987, the highway had been numbered as MT 87. The route had also been paved.[14]
