This is a short railroad bridge just out of Noti. The bridge was built in 1907 and trains still use the line today. In the past it was part of the Southern Pacific RR, but is now on the Coos Bay Rail Link (CBR). SEE http://bridgehunter.com/or/lane/bh50689/
Just down Vaughn Road a short distance from this bridge is the longer Noti Creek Trestle, built in 1912. I will get a photo of it when it works out. Finding an accessible parking spot is difficult very close to the trestle. Here is some information about this bridge: http://bridgehunter.com/or/lane/bh52205/
The rail line runs between Eugene and Coos Bay on the Oregon Coast. The father of a close friend of mine used to make this run as engineer, back in steam days and later.
