The following is a list bridges which may have parts that are older than we think. The main structures may be seventeenth or eighteenth century in style, but there is often no clear historical confirmation of this. What is confirmed, however, is that there was a bridged crossing at that location on Pont or Blaeu. In some instances we may have to reconsider the dating. These bridges are represented by maroon markers on the map. In some cases a red marker could have been used. There are 34 examples in alphabetical order, best seen individually on the catalogue map by looking for the coordinates.
