General Ulysses Grant crossed the original Monarch Pass on his mining town tour in the early 1880s.


The Monarch Pass Toll Road (original Monarch Pass) was a wagon road built by Sam and Hugh Boone in 1879 to provide access to the White Pine and Tomichi mining areas. It was opened in 1880, and in 1881, it became a stagecoach route.


By 1919, work began on a new, shorter route that would be less steep and dangerous. That route is known today as “Old Monarch Pass”. It opened to “automobiles” in 1921 and merged with the original road on the west side of the pass.


Finally, in 1939, a third crossing was constructed a little lower and to the east of Old Monarch.
