Driving Directions

The loop follows portions of State Highways 20, 49 and 89, historic U.S. 40, and Interstate 80. It is located in Nevada, Yuba, Sierra and Placer counties. It crosses historic Donner Pass and Yuba Pass. Much of the byway is over curving, 2-lane highways. Expect winter driving conditions along higher elevation stretches.

Highlights and Key Points Along the Route

Route travels through small towns in rural areas, many with mining-era history. Highway 49 crosses the three forks of the Yuba River on the west slope of the Sierra Range.

Historic U.S. 40 over Donner Summit was a portion of the transcontinental Lincoln Highway.

Tracks of the transcontinental railroad are visible from I-80 over Donner Summit, too, as this is a significant all-weather pass over the Sierra.

Many museums and several nearby State Parks highlight the historic, cultural, and natural resources of areas along this byway.

Access to recreation areas in some locations along the loop.

Eco-Friendly Notes

Nice fall colors throughout route.
