It looks like the problem is the concrete column.
What kinda of engineer would do that?
Must not have been a local. Those out of towners are always screwing things up.
I'm sure not an engineer but I'm thinking cost has something to do with it.
Wynoochee crossover bridge has the same type of pillar, right where the flow and "lots of wood" gets hung up every year. Wynoochee, old bridge at Black Ck. also had a old metal pillar, while not in the middle of the river, each year would have again lots of everything caught......new bridge has NO PILLAR, so someone learned something. Lower Wynoochee, 2 bridges with a pillar in the river.....yep causes problems there.
Thanks for whomever, posted the picture....I can see why that log would cause a problem.....
