The Last Wangdue Bridge

The historic wooden Wangdue bridge gave way to a motorable bridge in 1970s. The new bridge was perhaps a green iron bridge which stood there till 2002, when it was replace by the current concrete bridge.

How did I know the last bridge was green and made of iron? The answer is half submerged in the river (see picture). It is not only an eyesore near a very important site but also not a friendly foreign object in the river biodiversity. 

I am wondering why the rubble was left there. Who was supposed to clear it? Why was it left there? Was it ok to be left there in the river just like that? 

Rubble of the Last Iron Bridge

I can guess that the iron is of very good quality and given the opportunity some people might want to scrap it to pieces and use it for some purpose or simply sell it of. In Bajo town even septic tank covers are lost and a recent news reported that a home lost all its window grills, which suggest that iron is in high demand in scrap market. Then, why isn't that ugly bridge scrap lying there forever? There are at least few good tonnes of solid iron, and instead of letting it rust in the river and remain as an eyesore for ages why don't we let some people take it away for free?
