Upgrading mainland Europe's oldest iron suspension footbridge

Wissekerke castle park in Belgium contains mainland Europe's oldest remaining iron suspension bridge (1824). In 1989, after years of neglect, the Kruibeke town council bought the castle, park and finally, in 2006, the bridge. The Architectural Engineering Lab of the Vrije Universiteit Brussel (æ-lab) was consulted to put the refurbishment on the right lines and to check whether this bridge can stand the shift in function from private to public.
This paper places the pedestrian bridge within the framework of 19th century bridge construction, determines its historical value, characterizes the used materials by metallographic methods combined with tensile and hardness tests, re-analyses the structure, proposes strengthening strategies and concludes with a renovation proposal that preserves all of the authentic elements, causes the least visual impact, is durable and guarantees continued public use.
