^^^ I looked it up and you're right.
Left early today and got to SR50 on the Suncoast Trail around 8:30AM. Rode south. Decided to explore and be daring.

Rode down to this water station (between mile marker 7 and 8).
Then headed north. Didn't realize there were a few places where the trail was right next to the highway. Didn't bother me. I was just surprised to see two of these. I guess its because the road and the trail are "sharing" the same bridge.
Stopped at Extreme Bicycles for a few minutes, then headed for the car.
Rode a total of 46.3 miles.
