Highway 85 South in California

This is where 85 South used to end at Stevens Creek Boulevard.
Notice how the exit is as wide as the freeway itself.  For 21 years, the last part of 85 was basically a six lane wide connection between 280 and Stevens Creek Boulevard, and few people used it. The pavement stopped just north of Stevens Creek and in front of the end of the freeway was a giant mound of ice plant. The overpass was built in 1988 and 1989, not in 1973 when 85 was extended from 280 to Stevens Creek Boulevard (note that the South Valley freeway portion of 101 was also under construction at the same exact time, and both were six lane, concrete freeways.) The freeway name changes to The West Valley Freeway here.
