Significance: The Griggs County Bridge is a single-span, Warren type through truss bridge. The Warren type was commonly built on larger roadway systems in North Dakota in the period 1900-1940. Because of increased traffic and larger vehicles, this type of bridge is becoming inadequate and increasingly rare.
