The roundabout, which was previously at the centre of a major controversy over its possible removal, is being retained with improvements and widening to entry and exit roads, in a bid to improve the traffic flow through the junction more efficiently.
The schedule of works, which began earlier this week and is expected to last four days, will keep the roundabout largely open throughout the project.
The four ‘splitter’ islands on the entry points to the roundabout will be removed this week, to enable the improvements to be carried out.
During the first four days of the project (July 27-31), the A16 north and south will be subject of a two-way traffic signal.
Meanwhile, Station Road (east and west of the roundabout, heading towards Waltham and New Waltham respectively), will be closed between 7.30am and 7pm, during this four day period.
CR Reynolds Construction has been appointed as the main contractor. The company has appointed a public liaison officer, Chris Butts, for the duration of the project for any concerns relating to its operations.
The scheme is scheduled to be completed within six months, if not sooner.
