The San Tomas Creek Trail crosses under Highway 101 between Great America and San Tomas. I was headed to meet my wife at Tasman and Great America and took a leisurely ride along this trail. The previous time I met my wife over there - at the Amtrak station at Tasman and Lick Mill, I crossed on San Tomas Expressway. Stupid. San Tomas Expressway is near deathwish territory, the creek trail is nirvana.
I took this photo, notice the bumper to bumper traffic on 101. Sadly, a few minutes later I joined my wife, put my bike in her car, and ended up in that bumper to bumper traffic. At least we got to use the carpool lane.
There are more excellent photos on the website linked above (and here) One key photo is missing, however.... this one...
The creek floods in rainstorms and the trail floods in the underpasses. Even after the flood subsides, you need to exercise caution as a thin layer of wet slime will stay on the trail and be very tricky to navigate.
This is unfortunate, as the two adjacent crossings, Great America/Bowers, and San Tomas, are anything but pleasant. I have only crossed at San Tomas the once, and it sucked. Great America used to be me standard commute route when I worked at SandCraft at Tasman and Old Ironsides, I learned to manage it and it's not horrible but it's not great either.
