Two full, night time closures on the A43 in Northamptonshire are planned for later this week, so contraflow can be removed ahead of the British Grand Prix.

The F1 race takes place on the weekend of July 3 to July 6 and will see around 480,000 people in attendance at the Silverstone race circuit.

Hundreds of thousands of extra drivers will be using the A43 over the first weekend of July, so the decision has been made to remove the traffic management measures, which are currently in place to allow work on the Towcester Relief Road to continue.

To remove the measures, which include a contraflow system – where traffic flows on in the opposite direction in a specific lane – full overnight closures will be needed later this week

The British Grand Prix will take place at Silverstone on July 6.

A spokeswoman for Jackson Civil Engineering, the company responsible for the works, said: “As part of the ongoing Persimmon Homes Towcester A43 relief road scheme, there will be a series of full night time closures on the A43 to remove the contraflow in advance of the Formula 1 British Grand Prix, and traffic management will be overseen by Silverstone’s event traffic management contractor."
