Drivers are being advised to avoid parts of Islington on some days during the Olympics, as restrictions are brought in for the Olympic Route Network (ORN).

Pentonville Road, City Road, Wakley Street and part of Goswell Road will be made part of the ORN for seven days during the Games as roads which are normally part of the network are used for competitions such as cycling. The King’s Cross gyratory will also be affected.

Changes will include longer parking and stopping restrictions when the route is in operation, and some pedestrian crossing signals will be switched off.

The ORN, and the Paralympic Route Networks (PRN), will mean changes to the road network such as suspended turns and bus lanes.

Some of the route will be marked as Games Lanes, which are for the exclusive use of the Games Family – athletes, officials, media, sponsors and VIPs.

But the ORN and PRN, which comes into effect on July 25, should not mean that London cannot function normally.

Alex Williams, Transport for London’s director of borough partnerships, said: “Having the Games is the equivalent of having 20 world championships in London at the same time.

“It’s a twin task to keep London moving while hosting a successful Games.

“The commitment is to get every official to their event on time every time.

‘‘That is a core objective of us being a host city.

“We have 10,000 miles of road in London and 109 miles of that is Olympic Route Network.

“We think London can continue to function but we need to ensure athletes can get to events.”

The route will be marked with blue road signs indicating lanes that are part of the network and their hours of operation.

Lanes will also be painted with the Olympic rings, and variable message signs by the side of the road will also be used.
