Central Pacific Railroad served as the Western terminus of America's first transcontinental railroad, passing through the formidable Sierra Nevada Mountains. In all, 15 tunnels were blasted through solid granite. 

Thousands of Chinese from Kwantung Province were recruited by Central Pacific Railroad Company and became known for their diligence and hard work. In the second year of construction, nine out of ten workers on the CPRR were Chinese.

Constructed on 1,040 acres just 10 miles southwest of the city center, the Cleveland Hopkins Airport was the first major airport in the world to provide an integrated system of paved landing surfaces, lighted runways, and a terminal complex consisting of hangars and operating facilities. Overseen by city manager William Hopkins and Major "Jack" Berry - an engineer on loan from the U.S. postal service who eventually became the city's first Airport Commissioner - the project at first was called "Major Berry's Folly" by local residents because of its outlying location.
