“... hump in the highway like this?”
It’s a bridge. I think that’s Surfside. If I’m right, you go west off Galveston, pay the toll at San Luis, go way down to SS, turn right at 332 and there is that shot. (Usually it has less water on the road.)
You’re right, it’s Surfside, I read it in the caption in the other set of photos. Yes, it’s west of Galveston maybe 30 miles?
