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. The company's headquarters was located in St. Louis, Missouri.

The firm was the designer of the ill-fated I-35W Mississippi River bridge, Minneapolis, Minnesota, 1964 (collapsed on August 1, 2007).[1] The official report by the National Transportation Safety Board blamed the bridge collapse on a design error by the firm, resulting in the gusset plates having inadequate load capacity.[2]

Some other well-known projects of Sverdrup & Parcel include:

Sverdrup & Parcel was succeeded by Sverdrup Civil, which in 1999 was part of the merger between Sverdrup and Jacobs Engineering.
