This bridge, over the Clackamas  River, and owned now by Union Pacific, had seen better days.
The bridge is an abandoned remnant of a trolley line that connected Oregon City and Portland It stood for more than 100 years but had not been used since the 1950s.
There were hopes that it could have been restored and used as part of the trolley trail from Gladstone to Milwaukie

The steel truss bridge was part of a regional trolley line that was constructed in the early 1890s through Southeast Portland, Sellwood and into Oregon City. The bridge was likely built in the 1900s, but by the 1940s weight restrictions were imposed on the structure. In 1968, the Portland Traction Co. ran its last trains from Golf Junction in Sellwood to the Oregon City paper mill. That section of the trolley track was abandoned, along with the old bridge.
The line was purchased by Southern Pacific Railroad, which merged with Union Pacific in 1996.
Also known as the Portland Avenue Historic Trolley Bridge it was located on the Clackamas River between the cities of Gladstone and Oregon City.  The river  has eaten away at the footings of the 290 foot long, and 18 foot wide structure. With a history of neglect, the bridge was pulled down, before it fell down.

Heavy equipment yarded it up on to the bank where it was torn apart section by section, and hauled away.

All trace of the bridge, and its 1,000 tons of iron, steel, and concrete are now gone.
