Although non-stop rain is causing havoc elsewhere it has not driven Old Town High Street roadworks off course.
Those behind the one-way improvement project say it is still running to schedule despite the incessant downpours and will meet its March completion date.
The roadworks were brought to an abrupt halt at the end of last year after traders said the project was putting off shoppers during the usually busy festive season.
Emergency meetings were called between shopkeepers, Dacorum Borough Council, Herts County Council and contractors Jackson Civil Engineering after traders said the works – which had fallen behind the original schedule – were putting businesses at risk of closure.
It was decided to stop the majority of the work until the new year.
On Monday the High Street was closed to traffic for four weeks, although pedestrians, residents and those making deliveries can still gain access.
The project is a joint venture between the borough and county councils and will see a one-way traffic system introduced, new paving, more on-street parking, a new outdoor events area, improved lighting, signage, street furniture and landscaping, in a bid to transform the Old Town as a shopping destination.
