I was reading a while back where a guy was touring down on the Gulf coast of Texas and elsewhere. There were a number of places where there were long narrow bridges with no riding room but high speed traffic. Seems like he was on a recumbent trike, maybe had a trailer. Anyway, his solution was just to thumb a ride across the bridges. Half the vehicles are pickups with nothing in the back anyway, and he said that worked pretty well. I don't have that problem around here, though.

I remember my dad telling about one of the truss-type bridges down there in the Houston area where you could see where the paint was scraped up on the bridge from trucks hitting their mirrors there. I don't think that one is there anymore, though.
