A long series of wandering thoughts that started with reading today's Luann comic strip ended with me reading the Wikipedia article on the Millau Viaduct < en.wikipedia.org/wiki/Millau_Viaduct > . I was startled to find that the builders advanced the roadbed onto the bridge the same way that the feed dogs of a sewing machine advance fabric. Search on "wedge" to jump to the description.
