William S. Hewett was a major bridge contractor in the Minneapolis area from the 1890s until well into the 20th century. His firm designed and built a number of bridges for the Twin City Rapid Transit Company when it was electrifying and expanding its system around the turn of the 20th century.

Reinforced concrete bridges

Bridges built by Hewett's firm used included some of the earliest reinforced concrete bridges built using the Melan system invented by Viennese engineer Josef Melan and patented in the United States in 1894. Hewett probably became familiar with the Melan system when working with his uncle's construction firm in northwest Iowa. Hewett's firm also designed Bridges No. L-5853 and 92247 in Como Park in Saint Paul, Minnesota. These two bridges also crossed the Twin City Rapid Transit line.[1]

Hewett performed other pioneering work with reinforced concrete and prestressed concrete. In 1907, he formed the Security Bridge Company, and he established Hewett Systems in 1913.

Hewett also built the reinforced concrete Washburn Water Tower in Minneapolis.

gollark: Well, yes, but on the other hand consumers don't seem to actually care much. Especially on phones.

gollark: They are part of the general trend away from general purpose computers, which I very much dislike.

gollark: It might have a dedicated management port, but otherwise probably anywhere it's connected; why would you *want* a hardware firewall thing, though?

gollark: I'd assume the law is more about intent there, though, i.e. are you trying to break into someone else's stuff.

gollark: It is? Weird.
