Now celebrating 50 years of service, the Seattle Monorail was built for the 1962 Seattle World’s Fair to provide a crucial link between the fairgrounds and the amenities downtown. Since that time, it has become a beloved and frequently used form of transportation, carrying 1.9 million passengers in 2011.
The Seattle Municipal Archive has a wonderful photo set available on Flickr, featuring images from the 1962 World’s Fair and the post-fair Seattle Center.
