U. S. Army Bomber Modification Center, Holman Airfield,- Riverside Hangar Complex, Minnesota, St. Paul; 3M Aviation Department Hangar
The South Hangar is part of a two hangar complex that was constructed in 1942. The hangars were constructed using glued aminated timber arches, a creative response to a World War II steel shortage. The hangar housed the U. S. Army Bomber Modification Center and was known as the Riverside Hangar Complex. By the end of the war, 3,286 airplanes were modified, mostly B-24s. In 1945, the military began phasing out the center's operations.
After the war, Northwest Airlines used the Riverside Hangar complex as its overhaul base. In 1959, Northwest moved its operation to Minneapolis St. Paul International Airport. The following year, the 3M Corporation's Aviation Department leased the South Hangar. The South Hangar, as part of the U. S. Army Bomber Modification Center, is listed on the National Register of Historic Places.
