From Co.Exist:
The Luchtsingel is a footbridge in Rotterdam (in the Netherlands) with two unusual attributes. One, it is all wood–17,000 individual planks. And two, it is funded by individual donations, not the city’s coffers. Each piece has someone’s name on it.

The bridge is temporary, while Rotterdam gets together the necessary finances to build something permanent. But it’s likely the Luchtsingel will be around for a while. According to the city’s current schedule, the new bridge won’t be funded for another 30 years.
