I'm reassured to know this work's been passed by the Environment Agency, but very glad it's not happening later on in the year when the voles are more active. According to the workmen, it's a matter of replacing the paving slabs on the walkway with tarmac and putting in wide-spaced bollards. But I don't see how the latter's going to help reduce the number of trolleys in the brook, as Tesco claim. Waiting to hear!
And the trolley by the culvert is still there (unless it's another one).
