Signs

As I was going out to a concert last night, I noticed a strange sign chalked on the pavement where my cul-de-sac meets main part of St. Johns Road.  When I went out shopping this morning, I noticed several others, more or less identical, and I think all at street corners.

The sign looked a bit like <U, except there was a vertical bar down the middle of the 'U'.  In some versions the bar did not make full contact with the rest of the symbol.  Turned ninety degrees, it looked a bit like a Euro symbol with a circumflex accent.

My best guess is that it is some marking preparatory to some roadworks that are about to happen, marking pipes or cables.
