I680 North in Alameda County (Sinclair Freeway)
This is just past the summit on Mission Pass (600'.) This pass is not
very tall but it can get on your nerves sometimes.There is a weigh station just after the summit.

This is from 1/20/1990 and I scanned it off slides. The freeway was being widened in the center divide.
