Thanks! Interesting website and will have to browse through it.

That info. says the lanes would be 10' each. Sure *seems* a lot narrower than that. Makes sense with all the big logging and other trucks thundering regularly through there. No need for anyone to worry and slow down or stop.

Maybe it's a psychological/optical illusion thing with the bridge structure so close to the curb side line.
