The Puget Sound & Pacific Railroad swing bridge sits near the mouth of the Hoquiam River in Hoquiam, Wash.
Hoquiam is the western end of the line for the PSAP, and most of the rail traffic stops at the Port of Grays Harbor facilities on the eastern side of the river, to the left in the photo above. On the west, there is a small rail yard and a few sidetracks, which do get used to store empty cars, but not very often, so the swing bridge mostly sits open to allow boats to pass.
According to Bridgehunter.com, the swing bridge was built in 1908. I'm sure it was used a lot more often back in the day: the old dock pilings in the foreground of this photo used to support the dock of one of Hoquiam's lumber mills, and in the early 1900s, lumber was Hoquiam's raison d'etre.
You can see an old photo of the lumber mill and bridge at the Bridgehunter link above.
This photo of the bridge in the evening was part of a package of four photos that won the Steem Bangladesh Landscape Photography Challenge last week. The other three photos are daylight shots, taken from the opposite side of the bridge, looking back toward Hoquiam. You can check them out here, if you'd like.
Thanks for reading and have a wonderful day. :)
