Arboretum Sewer Trestle
The Arboretum Sewer Trestle is a historic multiarched concrete-and-brick trestle and footbridge in the Washington Park Arboretum in Seattle, Washington. It was listed on the National Register of Historic Places in 1982. It also has city landmark status, with ID #106070. As observed in a letter to the City Engineering Department in 1912, "The bridge is not an 'apurtenance of the sewer.' It is a piece of ornamental bridge architecture designed elaborately and is a very much greater thing than the sewer itself, in every way."
