The Spokane, Portland and Seattle Railway was chartered in 1905 by James J. Hill for the purposes of connecting the two transcontinental railroads owned by him, the Northern Pacific and Great Northern, to Portland, Oregon from Spokane, Washington, in order to gain a portion of the lumber trade in Oregon, a business that at the time was dominated by E. H. Harriman's Union Pacific and Southern Pacific railroads. Construction began in 1906 under the name Portland & Seattle Railway, proceeding eastward from Vancouver, Washington. 1906 also saw the start of construction of the line between Vancouver and Portland. This railroad included the first bridge of any kind to be built across the lower Columbia River: the bridge now known as the BNSF Railway Bridge 9.6, in Vancouver.
