The Missouri Pacific Building is a 22-story skyscraper. Construction began in 1926 and the finished building was occupied in 1928. Its design, by E. M Tucker with local architects Mauran, Russell and Crowell, features a roughly U-shaped plan above the second story moderated by a Series of setbacks. Prominent ribs at every second bay emphasize the vertical thrust of the building. The Gothic Revival style is conveyed through the ribs, which terminate in spires above the rooflines, but detailing and the overall massing is more closely identified with the Art Deco style. The exterior surface is clad with white terra cotta which is notable for its rippled, frosting-like texture. The rear of the building, which faces east, is blond brick. The main entrance at 13th Street is within the two-story base; at the second story above the front door is a half-scale relief sculpture which features a locomotive engine, images of railroad employees, and an eagle (the symbol of the Missouri Pacific line for many years). Historic interior spaces include the lobby and some of the executive offices at the top two stories. Most of the other spaces have been modernized and do not retain integrity. The exterior retains excellent integrity with the exception of replacement windows throughout and granite infill panels at the first story storefronts. The building was refurbished in 2011. - NRHP
