"On April 4, 1953, the first stage of Seattle's Alaskan Way Viaduct is completed. The viaduct follows the former route of numerous railroad tracks that ran along the Seattle waterfront. It ends near Pioneer Square about at Dearborn Street. The final phase, called the Spokane Street Extension or simply the southern extension, will be completed in 1959 and will extend the viaduct from its previous southern end to just north of S Nevada Street."
