Dr Michael Barker, P.E., provides a direct cost comparison between two nearly identical short span bridges (one steel bridge and one concrete) in Audrain County, Missouri. His findings show steel construction as the more economical choice. Furthermore, Steel Bridges provide significant cost savings over similar concrete structures.

Steel is widely used around the world for the construction of bridges from the very large to the very small. It is a versatile and effective material that provides efficient and sustainable solutions. Steel has long been recognised as the economic option for a range of bridges. It dominates the markets for long span bridges, railway bridges, footbridges, and medium span highway bridges. It is now increasingly the choice for shorter span highway structures as well. Society gains in many ways from the benefits delivered by steel bridge solutions. Landmark steel bridges embody good design, they are fast to build, and have stimulated the regeneration of many former industrial, dock and canalside areas.
Steel bridges are an essential feature of a country’s infrastructure and landscape. Few man-made structures combine the technical with the aesthetics in such an evocative way. Finally take a close look at the next ‘landmark’ bridge you see and the chances are that it is made of steel.
Burnco designs and builds modern steel bridges to take advantage of the latest advances in automated fabrication and construction techniques. These advantages are also economic solutions and meet the demands of the current safety standards. Steel also allows for rapid construction with much of the fabrication done off-site in controlled environments. Steel bridge construction also requires minimal maintenance and flexibility in future use. Steel is sustainable and offers a broad range of benefits addressing the economic, environmental, and social priorities of the ‘triple bottom line’ of sustainability.
