This is a good view of the flyovers. Prior to the early 1980s, surface
streets were used to access 280 and 680.
This is about a mile south of Alum
Rock Ave (130.)
Here US101 went from being very wide down to two very decrepit lanes
with 1942 vintage pavement, under Alum Rock Ave. The section from 280 /
680 to 880 (old Highway 17) was a doozy before about 1991.
