enemy number one is the salt that highway departments spread on the roadways each winter -ravenous stuff that keeps eating steel once it’s done with the ice. oil, antifreeze, and snowmelt dripping from cars wash salt into catch basins and crevices where maintenance crews must find and flush it. with no more people, there won’t be salt. there will, however, be rust, and quite a bit of it, when no one is painting the bridges.
