Building the Potomac Line

In my area, salt use has diminished over the last decade. If it often a mix of sand and salt that is used. All that salt was taking a serious toll on many infrastructures and bridge, and a environmental side-effect.

I toured buildings in downtown Montreal last week. It was quite impressive to see the extensive salt damage to buildings made of stone in urban context. Most of the degradation was quite recent due to increase in salt use. Even granite was decomposited by salt.
