Commonly known as the Kingsbury Grade, it is one of three Nevada highways that connect the western edge of the state to the Lake Tahoe region through the Carson Range.

SR 207 begins at a junction with U.S. Route 50 in Stateline, less than 1 mile (1.6 km) from the California state line near the southern shores of Lake Tahoe.

[1][3] A road connecting Lake Tahoe to the Carson Valley, situated in the approximate location of today's SR 207, appears on Nevada state maps as early as 1919.

[8] By 1968, the eastern end of the Kingsbury Grade was moved southwards to line up with what is now Mottsville Lane, mirroring the approximately 11 miles (18 km) alignment of the present highway.

[9] Following the realignment, the Kingsbury Grade section of SR 19 was not altered until the 1976 renumbering of Nevada's state highway system on July 1, 1976.
