[Harry Potter] How could the Death Eaters destroy the Millennium Bridge in 1996 when it was built in 2000?

Because it was also built before that. After the Death Eaters destroyed it (And after the wizarding war was over), the Ministry of Magic's Obliviators had to spend a few weeks removing any instances of that bridge from all of the muggles' memories. But because you can't just have an excavated spot for a bridge with no bridge, the MoM had to slip the building plans to the architects to get the bridge going again. This was probably one of the most mundane, yet difficult, tasks the obliviators have had in a long time.
