Alterations to lane markings at a Buckingham roundabout will start w/b November 23.
The work will be undertaken by the developers of the Lace Hill estate in response to an independent road safety audit and concerns raised by residents.
The alterations to the lane markings will create a dedicated left hand lane and two circulatory lanes at each entrance to the roundabout.
Buckinghamshire County Council has been reviewing the proposed revisions with the developers to ensure safety concerns could be satisfied without reducing the capacity and operation of the roundabout.
Mark Shaw, Cabinet Member for Transport, said: 'As the highways authority we had to be assured that the proposed revisions would aid safety at this junction. I'm satisfied the revised lane markings will make the road safer and easier for motorists to use.'
Although the roundabout is due to be resurfaced, the revised lane markings will be installed as soon as possible to satisfy local concern. Re-surfacing by the developers is scheduled to be done during the winter, subject to weather, along with the outstanding remedial works.
