I've seen those piers before and of course I always knew they were from an old bridge. Now, my question is, which bridge? You'd think this bridge was the first to span this part of the river when they realigned the railroad through here in the 1960s. Those piers couldn't have been an old hwy bridge either, because the current deck truss bridge allowed for US 2 to be realigned off of its old route along what is now Reiter Road, which, like the old RR alignment was on the N side of Skykomish River.
My only guess is that those old piers must have been a bridge that carried a spur railroad track that went to the quarries. Was this what those old piers were from?
