Why should you use steel for your next bridge construction project?
Economical: Short Span Steel Bridges are Cost-Effective on Several Levels.
- Due to the light weight of steel, cost savings can be significant: smaller abutments, use of local crews, fast installation, lighter equipment – when you add them all up, steel provides significant cost savings.
- Studies show that weathering, A1010, and galvanized steel reduces both initial and life cycle costs.
- Steel can compete and even save costs when compared with nearly identical concrete structures. A side-by-side comparison of steel versus concrete bridge showed a 19 percent savings by using steel in the total cost of the structure.
- Steel bridges also have long lives, decreasing the need for replacement. New press-brake-formed steel bridges have life expediencies of 100 years or more.
- Steel’s high strength permits longer spans, minimizing disruption to underlying habitats. In some cases, this can eliminate the need to undertake costly environmental impact studies.
- Steel is highly resistant to extreme natural disasters such as earthquakes. An example is the 1994 Northridge, California earthquake, which destroyed the surrounding transportation infrastructure but left 96% of the existing steel bridges completely undamaged, even though they were designed using 1940s technology.
- Steel is the world’s most recycled material and is infinitely recyclable, so it can be repurposed from one bridge project to another. Ohio’s Muskingum County Engineer’s Office (MCEO) estimates that $51,000 was saved in superstructure costs for replacement of the Green Valley Road Bridge.
- Short span steel bridges can be designed with prefabricated elements which provide a simpler installation and cost savings
Sustainable: Steel is North America’s Number #1 Recycled Material
- Steel from a disassembled bridge can be used again for another project. When Hurricane Ivan damaged the bridge over Florida’s Escambia Bay in Pensacola, contractors used 36-inch steel beams from a disassembled bridge in Tennessee to make substructure repairs. In Muskingum County, Ohio, five bridges have been replaced with repurposed steel, saving costs as well as resources.
- Press-brake-formed steel tub girder bridges can last 100 years or more, with minimal maintenance over their long service lives.
- The high strength of steel permits longer spans, which minimizes disruption to underlying habitats.
- Steel is highly resistant to extreme natural disasters such as earthquakes.
- The American steel industry has achieved a 31 percent reduction in energy intensity and a 36 percent reduction in greenhouse gas intensity since 1990.
