The New Brunswick Department of Transportation and Infrastructure (NBDTI) needed to replace a pair of old steel culverts at Red Bank Creek under Route 123 near Chipman. They opted for a pair of corrosion/abrasion-resistant Dur-A-Span Aluminum Structural Plate culverts as a more effective solution for this site’s very aggressive water chemistry.
Design service life of over 75 years
Made from solid aluminum alloy structural plate, Dur-A-Span, is ideally suited for your saltwater and aggressive soil applications. That’s because aluminum has a tough, self-healing, oxide surface film that reforms immediately if it is mechanically damaged or corroded in an aggressive environment like saltwater or harsh soils. This makes Dur-A-Span corrosion-resistant culverts virtually maintenance-free, with a design service life of over 75 years.
Chosen over reinforced concrete box culverts for all the right reasons — increasingly, smart specifiers recognize the many benefits of culverts made from Dur-A-Span:
- Solid, corrosion/abrasion-resistant aluminum
- Larger single opening, greater flow, less flooding
- No joint separation or differential settlement issues
- Bottomless, fish-friendly designs
- Variety of low-profile shapes, footings and end treatments
- Lightweight, easy to ship and install
- Low maintenance, improved life-cycle cost
- Proven in over 15,000 structures for over 20 years
