88 East in Amador County, California

This set runs from Jackson, California to Minden, Nevada. It is signed as 88 in California and Nevada. This highway is much faster than I ever anticipated. When I used to look at 88 on a map, I figured it was as slow as 190. I was wrong. Most of the way you can do 55 MPH. It has a very tall summit at Carson Pass (about 8500' up.)
I would not take a big rig up this road, but I have seen them up here. It is not as steep as 180 but has some climbs.

There is a short cut to 88, take Liberty Road off 99 (about 15 miles north of Stockton) to cut out a lot of slow driving.

88 is a higher speed highway than US50. This set is from 4/28/2001, and December 2004.
Fellow highway enthusiast  Joel Windmiller has his own "Adopt a Highway" section of 88, and he helped me clarify where my 2001 era photos of 88 were taken. Route 104 is proposed to run quite a bit east of Jackson.
