This year’s theme of bridges is well suited to Switzerland: there are around 3,000 bridges in the national road network alone, with over 8,200 bridges in the rail network adding to the total. Whereas bridges made of wood and later iron were predominant in the past, most modern bridges are constructed of concrete. The two Swiss EUROPA stamps combine old and new. Firstly, the Spreuer Bridge, built in Lucerne in the 13th century, is the oldest surviving wooden bridge in Europe following the Chapel Bridge fire. Secondly, the Trift Bridge
is one of the longest and highest pedestrian-only suspension bridges in the Alps. At 100 metres high and 170 metres long, it is recommended only for those with a head for heights (text: Swiss Post).
