US 187 was approximately 207 miles in total length, although AASHO's Apr. 1927 route log listed it as 265 miles:

US 187 was among the original 1926 routes, numbered as a branch of US 87W.  The south end of US 187 was always in Rock Springs, on Elk Street, at its junction with Bridger Street/Center Street (which carried either US 30 or Business 30):

The large image at the top of this page (from an old postcard) was taken when US 187 was still in existence.  The view was looking east on Center Street; the US 187 designation began to the left on Elk Street.  Here is an enlargement of the sign bridge:

Those sign panels were for northbound and eastbound traffic.  This more-recent photo was taken from the same intersection, looking roughly the same direction, except it shows the sign panels for eastbound and southbound traffic.  The truck was about to enter the former south beginning of US 187:

This photo was looking north on Elk.  The cross street is the main drag through town: former US 30, and modern Business Loop I-80.  The cars stopped at the light were about to enter what was once the south beginning of US 187:

That was a bit misleading, because it implies that Elk is US 191, but that is actually not the case until the north side of I-80 (which is about a mile ahead).  Technically, that segment of Elk is unsigned Spur US 191.
The north terminus of US 187 was always in Jackson Hole, although its specific endpoint changed in 1957 (maps, photos, and more info on the Moran Jct. page).  The US 187 designation was retired in 1982, when US 191 was extended southward along the entire length of what had been US 187.
