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.
URS Corporation was an engineering, design, and construction firm and a U.S. federal government contractor. Headquartered in San Francisco, California, URS was a full-service, global organization with offices located in the Americas, Europe, Africa, and Asia-Pacific.
Minnesota State Highway 36 (MN 36) is a 21.718-mile-long (34.952 km) highway in the U.S. state of Minnesota, which runs from its interchange with Interstate 35W (I-35W) in Roseville and continues east to its eastern terminus at the Wisconsin state line, where it becomes Wisconsin Highway 64 (WIS 64) upon crossing the St. Croix River at the St. Croix Crossing bridge. MN 36 is a major freeway in suburban Minneapolis–Saint Paul from its western terminus to its intersection with MN 120, at which point it becomes an at-grade expressway.
Interstate 694 (I-694) is an east–west auxiliary Interstate Highway located in the Minneapolis–Saint Paul metropolitan area in the US state of Minnesota. The western terminus of the route is at its junction with I-94, I-494, and US Highway 52 (US 52) in Maple Grove. The eastern terminus of I-694 is at its junction with I-94 and I-494 at the Woodbury–Oakdale city line. I-694 comprises the northern and northeastern portions of a beltway around the Twin Cities, with I-494 forming the remainder of the beltway. The speed limit is 60 mph (97 km/h). Interstate Highways outside of the loop in Minnesota may be signed as high as 70 mph (110 km/h) but can only reach 60 mph (97 km/h) inside the loop.
Carol Molnau is an American politician who served as the 46th lieutenant governor of Minnesota, from 2003 to 2011. As of 2024, she is the most recent Republican to have been elected Lieutenant Governor of Minnesota.
The 10th Avenue Bridge crosses the Mississippi River near downtown Minneapolis, Minnesota and also in proximity to the University of Minnesota. The bridge was historically referred to as the Cedar Avenue Bridge in the days prior to the construction of the I-35W Mississippi River bridge when it connected to Cedar Ave. The bridge connects 10th Avenue Southeast, on the east side of the Mississippi River, to 19th Avenue South on the west side. The Seven Corners area of the Cedar-Riverside, Minneapolis neighborhood is at the southern end of the bridge. The downstream end of the lower Saint Anthony Falls lock and dam extends under the bridge. The historic Southeast Steam Plant is also located nearby.
The Sidney Lanier Bridge is a cable-stayed bridge that spans the Brunswick River in Brunswick, Georgia, carrying four lanes of U.S. Route 17. The current bridge was built as a replacement to the original vertical-lift bridge, which was twice struck by ships. It is currently the longest-spanning bridge in Georgia and is 480 feet (150 m) tall. It was named for poet Sidney Lanier. Each year, there is the "Bridge Run" sponsored by Southeast Georgia Health System when the south side of the bridge is closed to traffic and people register to run the bridge.
Interstate 35W (I-35W) is an Interstate Highway in the US state of Minnesota, passing through downtown Minneapolis. It is one of two through routes for I-35 through the Twin Cities of Minneapolis and Saint Paul, the other being I-35E through downtown Saint Paul.
Leif Johan Sverdrup CBE was a Norwegian-born American civil engineer and general with the U.S. Army Corps of Engineers in the first half of the 20th century. He is best known for his service in the Southwest Pacific Area during World War II where he was Chief Engineer under General of the Army Douglas MacArthur.
CH2M, earlier CH2M Hill, was an engineering company that provided consulting, design, construction, and operations services for corporations and governments. The company was organized in Corvallis, Oregon, and headquartered at 9191 South Jamaica Street, Englewood, Colorado. In December 2017, the company was acquired by Jacobs Engineering Group.
The Hastings High Bridge was a continuous steel through truss bridge that spanned the Mississippi River in Hastings, Minnesota, United States. It was designed by Sverdrup and Parcel and was built in 1951 by Graus Construction Company of Hasting for $356,000. It was demolished in late 2013 when the current Hastings Bridge opened. It had been scheduled to be torn down and replaced by MNDot in 2019, but after the I-35W bridge collapse in Minneapolis, it was re-prioritized and construction started in 2010.
The I-694 Bridge is a pair of girder bridges that spans the Mississippi River between the cities of Brooklyn Center and Fridley in Minnesota. The westbound bridge was built in 1963 by the Minnesota Department of Transportation, and widened in 1987 with a new structure above the piers. The eastbound bridge was built in 1988, also by the Minnesota Department of Transportation.
The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967, and was Minnesota's third busiest, carrying 140,000 vehicles daily. After only 39 years in service, it experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The National Transportation Safety Board (NTSB) cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets. Additional weight on the bridge at the time of failure was also cited by the NTSB as a contributing factor.
DeSoto Bridge was a trussed deck-arch bridge that spanned the Mississippi River in St. Cloud, Minnesota. It was built in 1958 by the Minnesota Department of Transportation. The bridge was painted black, which is typical for railroad bridges but unusual for a highway bridge. The river banks on either side are relatively high, so the bridge required deep trusses which arched over the river.
HNTB Corporation is an American infrastructure design firm. Founded in 1914 in Kansas City, Missouri, HNTB began with the partnership made by Ernest Emmanuel Howard with the firm Waddell & Harrington, founded in 1907.
Interstate 335 (I-335) is a canceled auxiliary Interstate route in Minneapolis, Minnesota. It was planned to cross Northeast Minneapolis from I-35W south of Broadway to I-94 in North Minneapolis. Land was acquired and some demolition had proceeded when the road was defeated by local opposition.
The I-35W Saint Anthony Falls Bridge crosses the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota in the U.S., carrying north–south traffic on Interstate 35W. The ten-lane bridge replaced the I-35W Mississippi River bridge, which collapsed on August 1, 2007. It was planned and is maintained by the Minnesota Department of Transportation (MnDOT). The planning, design, and construction processes were completed more quickly than normal because Interstate 35W is a critical artery for commuters and truck freight. The bridge opened September 18, 2008, well ahead of the original goal of December 24.

The city of Minneapolis, Minnesota, is covered by a citywide broadband wireless internet network, sometimes called Wireless Minneapolis. The network was first proposed in 2003, at which point only a few other cities nationwide had such systems in place. Local firm US Internet beat out EarthLink to build and operate the network, with a guaranteed ten-year, multimillion-dollar contract from the city itself as the network's anchor tenant. Construction began on the project in 2006, but encountered several delays. Most of the city was covered by the network by 2010, and USI Wireless, the subsidiary of US Internet responsible for the system, set up numerous free internet access points at public locations around Minneapolis.
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load without breaking and includes the study of past structural failures in order to prevent failures in future designs.
