North Fork East River Bridge
Posted August 7, 2018, by Kyle Jarvis (kylejamesjarvis [at] mail [dot] com)

I doubt the 1939 build date for this bridge. There are no dates on the bridge, and 1939 would mean that this bridge was built after the Upper West Branch bridge on highway 57, which is a much more modern design. The style of this bridge, along with it's low 12"1' clearance and very light weight rating, combined with the 1925 date for the construction of the Dickensheet Bridge up stream, both of which are part of the old road from Priest River, ID to Coolin on Priest Lake, would lead me to think this bridge was built probably in the mid 1920's.
