Sverdrup & Parcel was an American civil engineering company formed in 1928 by Leif J. Sverdrup and his college engineering professor John I. Parcel. The company worked primarily in a specialty field of bridges. Many of the company's projects were located in the St. Louis, Missouri area near the company's headquarters.
The firm was the designer of the ill-fated I-35W Mississippi River bridge, Minneapolis, Minnesota, 1964 (Collapsed on August 1, 2007).[1] Preliminary findngs of the National Transportation Safety Board blame the firm's gusset plate design for the bridge collapse.[2], [3]
Some other well known projects of Sverdrup & Parcel include:
- Amelia Earhart Bridge 1939, Atchison, Kansas
- Sidney Lanier Bridge 1956, Brunswick, Georgia
- Bridge of the Americas 1962 (also known as Puente de las Américas, Thatcher Ferry Bridge), Panama, crosses the Panama Canal
- Chesapeake Bay Bridge-Tunnel, (also known as Lucius J. Kellam, Jr. Bridge-Tunnel) completed in 1964, and named one of the "Seven Engineering Wonders of the Modern World" shortly thereafter.
- Puente de Angostura Bolivar, Venezuela, crosses the Orinoco River
- Louisiana Superdome, New Orleans, Louisiana, 1975
Sverdup & Parcel was succeeded by Sverdrup Civil, which in 1999 was part of the merger between Sverdrup and Jacobs Engineering.
