From 16-20 April, the Commonwealth Heads of Government will be meeting in London. There will be a significant impact on St James’s Park and The Green Park between Sunday 15 April and Friday 20 April.

For full information, please read the event fact sheet or visit the Commonwealth Heads of Government website.

Vehicle access into the Parks will be restricted over the course of the event. On occasions when there are specific events being held within the Parks or at the Commonwealth Village, the Parks will become predominantly traffic free, with access only available for vehicles with approved accreditation.

Road closures inside St James's Park will remain in place until the afternoon of Monday 23 April, due to the London Marathon taking place on the Mall on Sunday 22 April.

Road closures will be advertised in advance and diversions sign-posted; however, road users should seek alternative routes or consider other modes of transport over the course of the event to avoid delays.

Pedestrian access through the Parks will be maintained from all entry points throughout the event; however, on some days pedestrians may be delayed at crossing points or directed to take other routes. These alternative routes will be clearly sign-posted.

All pedestrian routes through St James’s Park will be open. In The Green Park, pedestrian routes south from Piccadilly through Queen’s Walk will close at key times; these will be advertised at the gate by Green Park Station and alternate routes will be sign-posted. It is likely to be particularly difficult to cross between St James’s Park and The Green Park on the morning of Thursday 19 April, and we would advise that alternative routes are sought on this day.

When vehicle restrictions are in place, the Cycle Superhighway will also be suspended. Cyclists will be asked to dismount and either walk or seek alternative routes.
