Here is one of the postcards I paid slightly more than 50cents to have in my collection. (previous post tells of my postcard show adventure) This is the (McQuesten) High Level Bridge built in 1931 that I cross at least twice a week, though in a much faster moving vehicle. The road below the bridge is now highway 403.
1905 was a year for building bridges in Iceland and this first stamp celebrates the 100th anniversary of the building of one of Iceland's three major transportation bridges. Lagarfljót is a lake in the eastern part of Iceland and the first suspension bridge across it was built in 1905. It was 300 m long and all the timber and iron had to be transported over hills and wasteland. The biggest forest on the the island can be found near this lake as well as one of the tallest waterfalls, the Hengifoss. And it even has its own serpent known as Lagarfljótsormur or Lagarfljót Worm.
and two other stamps featuring bridges, one from Russia and one from China. I have given up trying to search through the internet trying to find anything on these stamps, so just enjoy the image.
