Description 

The Muddy Fork Sandy River Bridge is significant due to the modern use of a truss span to replace a damaged reinforced concrete girder bridge.

Though the truss fabrication and construction techniques are modern, the use of a truss span on a highway bridge within Oregon is a rarity. Most structures of this type would have been replaced with a simple pre-stressed concrete slab structure with little or no esthetic value.
