Nik Wallenda's tightrope walk above busy US road

American tightrope walker Nik Wallenda has pulled off another stunt - by doing a high-wire walk over a busy road with NO safety harness!

The daredevil circus performer's rope was suspended 61 metres in the air in his hometown of Sarasota, Florida.

It took him about 15 minutes to get to the other side, battling a slight wind.

Nik successfully walked across the Niagra Falls last year, but he used a safety harness for that one.
