Finchley Road is a designated 4.5-mile arterial road in north-west London, England. The Finchley Road starts in St John's Wood near central London as part of the A41; its southern half is a major dual carriageway with high traffic levels often frequented by lorries and long-distance coaches as it connects central London, via the A41 Hendon Way, to the M1 motorway at Brent Cross and other roads at that interchange.
