It was listed on the National Register of Historic Places in 1997.[1] According to its NRHP nomination, the bridge "is a two-span concrete T-beam structure, some 66 feet long. Concrete T-beam designs saw occasional use in North Dakota during the first half of the twentieth century, as bridge builders began experimenting with the increased use of reinforced concrete in heavy load-bearing applications."[2] It was listed on the National Register of Historic Places in 1997.[1] It is owned and maintained by Pembina County.[2][3] References1. ^1 2 {{NRISref|version=2010a}} {{National Register of Historic Places}}{{NorthDakota-NRHP-stub}}{{NorthDakota-bridge-struct-stub}}2. ^1 {{cite web|url={{NRHP url|id=97000507}} |title=National Register of Historic Places Registration: Crystal Bridge| date=December 10, 1996 |author=Mark Hufstetler}} and {{NRHP url|id=97000507|title=accompanying photos|photos=y}} 3. ^{{cite web| url={{NRHP url|id=64500380}} |title=National Register of Historic Places Multiple Property Documentation: Historic Roadway Bridges of North Dakota |author= Mark Hufstetler |date=December 10, 1996 |publisher=National Park Service}} 7 : Road bridges on the National Register of Historic Places in North Dakota|Bridges completed in 1927|Buildings and structures in Pembina County, North Dakota|National Register of Historic Places in Pembina County, North Dakota|Road bridges in North Dakota|Concrete bridges in the United States|1927 establishments in North Dakota |
