130 East  (Mount Hamilton Road) in California

This set is from 10/18/1986.
This was unfortunately a smoggy day. This road does eventually run to I5, Patterson, and Turlock, but the section from Mount Hamilton Road to I5 is not suitable for trucks or oversize vehicles. The road gets much wider and faster after Mount Hamilton. This road can be closed due to snow in the winter. It's a secondary road so riding on it with chains is a bit more dangerous than riding on I80 with chains. This road has the same type of recessed pavement markings as a few "guinea pig zones" of I80. Speaking of pigs, I have seen families of wild pigs crossing the road near Grant Ranch County Park.
This is on Alum Rock Ave, in East San José which is an unincorporated neighborhood east of I680. It is an hour to Mount Hamilton from here. It is one hour 20 minutes from Mount Hamilton to Interstate 5. Update: This area burned in August 2020.
You pass through a rough area of San José before reaching this area.

The first section of Mt. Hamilton Road is about 40 MPH. It has a lot of wide curves and steep drop offs. The westernmost part of Mt. Hamilton Rd has been developed extensively during the late 1990s.
After about  Three Springs Road, it is a 20 MPH road. Its a narrow two lanes. The road never is really steep since this was built on a very old road used to build the observatory. However if you are afraid of heights you cannot take this in all likelihood. And I mean even as a passenger. However past Mount Hamilton you should be able to handle it if you drove here via the San Antonio Valley instead. Be aware that takes hours.
