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

Our 2016 ‘culvert crawl’ takes a closer look at four Dur•A•Span structures that were installed in BC’s lower mainland in 2005. All culverts are in excellent condition and performing well. Take a closer look at their condition and water test results here.
