Elmbourne Road - roadworks, or trial road closure?

This afternoon coming back from Balham, I noticed these roadworks taking place at the north end of Elmbourne Road. Thames Water are doing some emergency works which has meant that the road has been closed at this point, but you can still walk or cycle past, and indeed park your car in front of, or nearby the properties adjacent to the works.

Approximate location of the works

Roadworks, or trial road closures are happening all the time, and we just adapt to them. That is why I don't believe that the fears of chaos caused by piloting low-traffic zones or home-zones will actually happen.

I'm looking for more support for the petition in the link below, which happens to be calling for a pilot in the very same area. If you live locally, I do hope you can support it.
