Here is a hot tip for driving from the Bay Area:
Forest Route 5, in El Dorado N.F., is a neat shortcut that we use in the Summer months. It starts about 10 miles east of Placerville on US 50, at Sly Park, and connects with highway 88 West of Carson Pass and the ski resort. The road is actually better than US 50. After exiting at Sly Park, it winds a bit through the residential areas until reaching Sly Park dam. Watch the signs for the correct left turn toward highway 88. There is almost no traffic on this road, and it avoids the mess at South Lake Tahoe. On reaching highway 88, turn East and proceed to Minden and US 395. You will save considerable time on this shortcut.
It is a wide, paved road.
