Arboretum Sewer Trestle

The Arboretum Sewer Trestle (also known as Arboretum Aqueduct, Arboretum Aqueduct and Sewer Trestle, or Wilcox Footbridge ) 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 (NRHP) in 1982 (ID #82004229). 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."

Accident
On April 16, 2008, a charter bus carrying the Garfield High School girls softball team crashed into the trestle, injuring a number of passengers and shearing off the bus's roof.
