There has been a number of curved and interesting footbridges built recently here in Melbourne. See these pics:
The last of these bridges is curved and the load carrying deck (pedestrians and bicycles) creates significant torsion on the main support spine.
This bridge won a LSAA Design Award in 2016.
However, up in Vietnam, a new elevated footbridge in a heavy tourist region has some big hands appearing to support the bridge.
