National Highways have confirmed details of a crowd control one-way system on the A43 near Silverstone for the British Grand Prix.

The Formula One event at Silverstone is expected to bring a large crowd to the track on the Buckinghamshire/Northamptonshire border, with organisers expecting a total attendance of around 400,000 people over the 3 days, and with tickets to Saturday’s qualifying session and Sunday’s Grand Prix race day sold out.

The event runs from Thursday (30 June) to Sunday (3 July), and in order to ease congestion, a one-way system will be introduced on the main A43 with extra traffic officers patrolling the area to deal with any incidents.

To ease traffic congestion, the A43 northbound will be one way from the B4525 interchange to Silverstone on both Saturday and Sunday from approximately 7am until around 1pm. The A43 southbound will be closed to through traffic at Silverstone.

From approximately 2pm until 8pm, the A43 southbound will be one way from Silverstone to the B4525 interchange while the A43 northbound will be one way from Silverstone to Towcester/BP roundabout.

Local people are also being warned of a one-way system operating on Dadford Road South from Friday through to Sunday. For latest details visit

National Highways have also confirmed that they will have a stand at the Grand Prix taking road safety messages directly to motorsport fans.

National Highways Network Resilience Planner, Jamie Tomlin, said, “This is the biggest date in the motor racing calendar in this country and many thousands of people will be heading to Silverstone this weekend with a large number using our roads.

“We are working closely with Silverstone to manage traffic flow and would urge people travelling to the circuit to follow the signs on the motorways and their car parking pass rather than sat navs. Whilst sat navs will get them to the circuit, depending on which car park is required they may need to leave by different slip roads.

“People should allow extra time for journeys and make sure they are properly prepared, for example carrying out pre-journey vehicle checks and carrying bottled water, particularly in hot weather.”

In the announced schedule, the race will be supported by feature events in FIA feeder series Formula 2 and Formula 3, women’s racing event W Series, and the Porsche Supercup.

The British Grand Prix will be held on Sunday (02/07), with the race scheduled to start at 3pm. Coverage will see the race broadcast live by Channel 4 and Sky Sports on UK television.
