Location

The Arboretum Sewer Trestle (also known as Arboretum Aqueduct,^[2] Arboretum Aqueduct and Sewer Trestle,^[3] or Wilcox Footbridge^[3]) is a historic multiarched concrete-and-brick trestle and footbridge^[3] 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.^[2] 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."^[4]

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.^[5]
