Hacienda Bridge (River Road in Sonoma County)

[Max Rockatansky]

The Hacienda Bridge was constructed by the Northwestern Pacific Railroad in 1914 at the Russian River near Hacienda siding.  During the mid 1930s the rails atop this structure were removed from this span and Sonoma County would repurpose it was part of River Road in 1945.  This truss was widened to two-lanes in 1948 still carries River Road over the Russian River.

This was very interesting to read about. I have family with a house in Forestville, and I have both crossed this bridge and floated beneath it on the river countless times.  I have often wondered about its history.  Seeing the photos in this article filled in a lot of the blanks for me.

FWIW, I consider River Road to be a superior route between US-101 and Guerneville compared to CA-116.
