|Route outline (key)|
The road starts at its western end at the the Northwick Park Roundabout. The A404 is both south and west and the A409 is north, whilst the A4006 heads east along Kenton Road. Roads that have the name of a place followed by "Road" can sometimes be in that location or can lead to that location. In this case it is generally "in the location", so it is called Kenton Road through Kenton and Kingsbury Road through Kingsbury.
Much of this road is 2 lanes each direction but not a dual carriageway and the speed limit is 30 mph throughout, with a few occasional speed cameras to enforce it.
In spite of being a fairly long road, it does not meet any other A-roads along its route until it meets the A4140 over halfway along the road at a roundabout known as Kingsbury Circus, which also has a fifth exit, an unclassified road called The Mall.
Just east of this junction is the busiest section as the road passes Kingsbury station and some shops, then has a couple of sets of traffic lights including a junction with the Kingsbury version of the B454, the only other classified road it meets except at the ends, before continuing eastwards to meet the A5 in The Hyde where it terminates. At this signalised crossroads is the option to continue along the unclassified road straight ahead, which is one-way and takes you into the Homebase superstore. It will also take you through to the A5150 to continue your journey east if that is the way you wish to go.
