Motorists are being warned of the potential for long delays north of Northampton due to roadworks associated with a housing development which are scheduled to start on Tuesday, after Easter.
Drivers are being advised to avoid the route if possible or allow extra time for journeys while the works take place at the busy Boughton roundabout.
The junction will be under round-the-clock temporary traffic signals as a new roundabout is built to allow better access into the new Buckton Fields development.
Councillor Michael Clarke, cabinet member for transport, said: “The temporary traffic lights on the A508 at the Boughton roundabout are extremely regrettable. I realise that this is the second time in as many months that motorists have been inconvenienced on this route.
“At Highways we work proactively with the many contractors and utility companies, who are involved in the construction of a large housing project such as the Buckton Fields development.
“We urge the contractors to exchange information and to cooperate with one another, so that we minimise the need for temporary traffic lights – and minimise the ensuing delays, especially at peak times.
“The sheer complexity of the projects and the number of contractors involved sometimes requires Highways to issue more than one permit to allow work to be completed. We will be doing all we can to get the work completed early and the temporary traffic lights lifted.”
The initial part of the project will focus on the Boughton roundabout junction and will need four-way temporary traffic signals.
The latter part of the project will concentrate on the section of Harborough Road further south of the roundabout and will need two-way signals. Work is scheduled to finish in early June.
