Chuck Seim has the rare distinction to have worked on all ten automobile bridges spanning the San Francisco Bay. He was born in 1925 in Los Angeles, California. The child of working class parents, he determined at a young age that he wanted to become an engineer. Following a stint working for the Army, he enrolled at UCLA to study engineering. He transferred to Berkeley in 1951 before completing his degree, deeply inspired by several key faculty members – including the renowned structural engineer T.Y. Lin. Soon, Seim was working for the Division of Bay Toll Crossings – starting a lengthy career in civil engineering, with a specialty in long bridge spans. Seim eventually became an independent consultant who advised bridge construction projects throughout North America and internationally in Asia and South America. Bridges discussed in this interview include the San Francisco-Oakland Bay Bridge, Golden Gate Bridge, Richmond-San Rafael Bridge, Dumbarton Bridge, Carquinez Bridge, San Mateo-Hayward Bridge, Martinez-Benicia Bridge, San Diego-Coronado Bay Bridge, the Ruck-a-Chucky Bridge, High Bridge (St. Paul, MN), 35W Bridge (Minneapolis, MN), Silver Bridge (West Virginia and Ohio), Rama IX Bridge (Bangkok, Thailand), Strait of Gibraltar Crossing (Spain and Morocco), Miles Glacier Bridge (aka “Million Dollar Bridge” Alaska) and the Brooklyn Bridge (New York City, NY).
