Map of road over Monitor Pass

From the Nevada Appeal, 10 February 2016:

Completion of 17 1/2 miles of new highway which connects by a more direct route the county seats of Bridgeport in Mono County and Markleeville in Alpine County will be celebrated by the boards of supervisors of the two counties with a dedication ceremony Sunday, when the new road will be opened formally to traffic.
The new highway, built over tortuous mountain terrain, extends from US 395 north of Coleville in Mono County to the Ebbetts Pass Highway south of Markleeville in Alpine. It has been designated a portion of State Route 89.
Hitherto, the only feasible route between Bridgeport and Markleeville was via Gardnerville, 27 miles longer than the new route.
The highway will provide more direct access from southern California to the recreational areas in the vicinity of Markleeville and Lake Tahoe, and to Carson City.
