The Main Drainage Channel of the Sanitary District of Chicago is crossed by 3 railroads. The Pittsburg, Cincinnati, Chicago and St. Louis; Chicago Terminal Transfer and the Chicago Junction Railways. The first having the western four tracks and the others having the next two each easterly tracks. Making a total of eight tracks crossing the channel. From this is derived the name of the structure.
