In contemporary times, one of the city's foremost and influential architects has been Warren C. Heylman, who helped give the city a great breadth of mid-century architecture. Heylman's career was most prolific during the 1960s and 1970s where his main body of work was done in the modernist style, designing numerous residential houses, apartment buildings, and architectural embellishments. Some of his most noteworthy works in Spokane include The Parkade, Spokane International Airport, Spokane Regional Health Building, and the Burlington Northern Latah Creek Bridge over Hangman Valley.
