@lucy_inthesky1 @lucy_inthesky1 Hi Lucy, yes into London from M25/M4 interchange is fine. Post navigation National Highways: South-East retweeted: Traffic stopped #M25 clockwise between J21A to J22 near #Watford due to a @HertsPolice incident. We’ll keep you updated. @SurreyPolice Police have removed their block however 3 lanes remain closed at the scene. Please take care on approach. Thanks for your patience.
