Environmental Benefits-Grace bridge

The demolition of the Grace Bridge began in August 2005. It took approximately two years and required closing the shipping lane for half a day so tha the main span could be cut from the cantilever sections, on to a barge below and shipped to[gs steel inline="false"]   mill as raw material.


Of the steel used in the bridge, 18,970 tonnes was [gs recycled inline="false"]  resulting in a saving of 33,460 tonnes of CO2 that would have resulted from producing new steel from iron ore.

Most of the rest of the steel (aproximately 20,000 tonnes) was taken out to sea to form an artificial reef for marine life and to protect the shoreline at the mouth Cooper River.
