After completing the entire route of CA 17 I took I-880 north to CA 237 where the route becomes the Southbay Freeway in Milpitas. As a full route CA 237 is only 11 miles long and traverses from I-680 west to CA 82/El Camino Real.  From I-880 west CA 85 the alignment of CA 237 is a freeway with a very short expressway segment before the western terminus at CA 82.  East of I-880 to I-680 the alignment of CA 237 is on Calaveras Boulevard. My route was on CA 237 west to US Route north on the Southbay Freeway which begins immediately west of I-880.  Oddly the junction of I-880 and CA 237 doesn't include ramps for northbound I-880 traffic but does for southbound.  Supposedly the freeway is up to Interstate standards but thankfully Caltrans hasn't attempted to apply for another mis-numbered Interstate like I-238 to the north.  The Southbay Freeway has express lanes but was heavily clogged during rush hour traffic from cars attempt to merge. ...

Back in 2018 I had an opportunity to drive the entirety of California State Route 17.  California State Route 17 was once one of California's important State Highways with segments eventually becoming part of Interstate 880 and Interstate 580.  Part 1; a drive on CA 17 CA 17 is 27 mile State Highway from CA 1 in Santa Cruz north to the junction of I-280/I-880 in San Jose.  CA 17 is a heavily trafficked highway with approximately 54,000 to 197,000 vehicles a day in the 1990s according to CAhighways.org.  CA 17 was once a far larger route previously which traversed the corridors now occupied by I-880, I-80, and I-580 to reach US 101 in San Rafael.  CA 17 even had an unbuilt segment that could have reached the outskirts of Point Reyes.  CA 17 is somewhat infamous due to it's current haggard expressway design in the Santa Cruz Range which begins north of CA 1. From CA 1 I jumped onto CA 17 north which still has Oakland as a control city 75 miles n...
