I used to commute Hwy 17 out of Santa Cruz county about 30 years ago. It was a major commute road back then, and still is now. Through to the 1940s there was a train line over roughly the same route, and in the 1990s there was talk of reopening the line for commuters.
Back then various locals managed to shut down any chance of the rail being restored. And of course Hwy 17 is still the dangerous nightmare it was 30 years ago.
And they are still fiddling with Hwy 17 trying to reduce (but never stop) the carnage.
