There is still no indication when a main road in Hemel Hempstead which was closed when the start of a sinkhole appeared last month will reopen.
High Street Green in Adeyfield was closed on May 12.
Rob Smith, Deputy Director of Environment for Hertfordshire County Council, said: “Although the hole in the road surface is quite small, the void underground extends for more than half the width of the road. As a result, the road remains closed and the area around the hole is fenced off to protect residents and road users while specialist teams complete a series of investigations. Local residents are being kept up to date with the latest information as we have it;
He added: “We expect the investigations to be completed by the end of the month and to be able to give a further update shortly after that. In the meantime we are monitoring the situation and working closely with partners in the area including Thames Water and Dacorum Borough Council.”
