At the turn of the century "Downtown" was on the west side of the tracks, as were the best residences and several churches. On the east side there were more commercial establishments, many being of a kind not desired on the west side, such as the "walled city" red-light district, a number of saloons and houses of minorities. Being a railroad town, in the 1910s and 1920s Pocatello became a city of cultural diversity with communities of Blacks, Greeks, Italians, and Chinese. This mosaic flavor remains today, with the addition of University Professors.

(left) East end of Center Street Viaduct, spring 1914. Note the Mansard Roof of the Pacific Hotel, which had to be partly destroyed to make way for the viaduct. The old freight depot is north of the Pacific Hotel, with the peaked roof. The right angle bend was required by East Center Street merchants who feared they would be cut off from business if the east slope of the structure were continued to street level. Pocatello economic development has always been difficult, and sometimes stupid decisions had lasting impacts. This was one. Bannock County Historical Society Collection.

The Kane Building, built in 1915, is the white brick structure on the south side of West Center. The hand written date on the photo is incorrect. Bannock County Historical Society Collection.

(upper right) West side of Center Street Viaduct over the Union Pacific tracks, summer 1912. This viaduct was the source of the term "going over town." Note the Indian riding a horse accompanied by his dog on the sidewalk. Three early motorcars are on the crest of the bridge. The Pacific Hotel (reduced in size) can be seen north of the viaduct.

The Center Street Viaduct
The Center Street Viaduct and the Halliday Street Subway were built in 1911 by the Union Pacific Railroad, on contract to the city of Pocatello, to allow traffic to cross the tracks without danger or interference with railroad operations. The viaduct opened Oct. 3, 1911, and the subway in August, 1911. The viaduct was replaced with the present subway in 1934.
