Soil-steel bridges vs conventional reinforced concrete bridges – Environmental impact issues

By using lightweight corrugated steel structures instead of concrete, both energy consumption in
manufacturing and installation as well as CO2 emissions can be reduced. A comparative life cycle analysis
study of corrugated steel structures and reinforced concrete pipes for an underground stormwater drainage
pipe (diameter 1.8 m, length 11.8 m) for the North American market confirms this.
