NCSPA Spotlight Spiral Rib Pipe Skunk Creek

NCSPA’s Project Spotlight Skunk Creek

Skunk Creek Crossing, ND

The North Dakota Department of Transportation had a problem with joint separation and spalling concrete in a 10’ x 8’ cast-in-place reinforced concrete box culvert built in 1934, and extended in 1960. To remove and replace the concrete box would have been time consuming and expensive.

To satisfy the hydraulics of the crossing the DOT wanted to use spiral rib pipe, along with aluminized type ll coated steel to extend the service life for an additional 75 – 100 years.
