PNWR - Clatskanie River Bridge
Posted December 3, 2015, by Julie Webster (jwebster [at] clatskanie [dot] com)

This bridge is turned with a large, heavy, metal bar that is angled, and has a square opening that fits over a peg from the center of the gears located below the deck. The operator puts the square opening over the peg, and walks in a circle, using the metal bar in front of them to push against, and move the bridge span. The bridge slowly moves into place as the operator walks it into position. It is then locked into place for the train to go over at no more than five miles an hour. Then it is unlocked, and moved back again, so river traffic, including tall sailboats, can maneuver through. I was a bridge-tender for two years for the Lewis & Clark excursion train, and enjoyed working with this bridge.

Looks like 1897 to me.

Here is a little blip from the Astoria Railroad Preservation Association's website....

"By 1898, a local industrialist named A.B. Hammond had built 50 miles of track along the Columbia River connecting Astoria with the tiny town of Goble and, more importantly, the Northern Pacific Railroad."

My guess is it is 1897--I have a relative with an old regulator clock, and the 7 also is the same as the 2 flipped upside-down. I suppose then they only needed one stamp for 2 numbers.

I looked at the pictures and the number 1 and 9 are both orientated the correct way. Might it actually be 1897?

The bridge is listed here as being built in 1895, but the date plaque has the date 1892. I wonder if it's because, with the bridge being in the open position then the date plaque would be viewed from behind and backwards, hence the 1895 date?

This and two other similar bridges between Portland and Astoria are manually turned with a ten foot bar or pole.

Very unique swing span!

The track curves through the draw span. Very unusual.
