8th Street Bridge
Description
The 8th Street Bridge over the Umatilla River in Pendleton replaced the over 100 year two span pin-connected truss at the same location in 2019.The structure pay homage to the original truss bridge with a single span weathering steel Warren through truss. There are single pre-stressed concrete approach spans on each approach and an attached pedestrian walkway along the downstream side of the bridge.
Through the structure replaced a cherished historic bridge for the region, the new structure is a beautifully designed structure that enhances the site with the addition of pedestrian facilities and an undercrossing for the river walk along the Umatilla River.

I still feel this is a sad outcome. I hope this isn't the future for the Oregon Coast Highway Conde McCullough bridges too. I would have preferred to see the original pin-connected Pratt trusses widened and placed on a bridge as decorative elements, thereby preserving one of the last pin-connected highway trusses in Oregon, an outcome that has been done in other states like New Jersey. The design of the replacement truss lacks the character-defining features of the historic truss including but not limited to a Pratt truss configuration, pin connections, and built-up beams with lacing. The new bridge design is pretty standard, they might not be common in Oregon, but many states out east build welded/bolted modern trusses, some in large quantities.
The modern truss would have been a great solution, IF the historic trusses were relocated and preserved elsewhere. But I do not believe this is the case here.
Oregon has traditionally had a good preservation track record, I am concerned... why is there suddenly this effort to destroy historic bridges? The other one at risk is the Van Buren Street Bridge, a swing bridge that also has pin connections. In the context of Oregon, pin-connected trusses are one of the rarest bridge types in the state. Does this count for nothing?
