This article is about the current B452 from Brentford to Perivale.
For the original B452 from Willesden to Neasden, see B452 (Willesden).
The B452 is a residential link road in west London. The road was originally unclassified but appears to have gained its number in the mid-1920s, making this an early example of a recycled number.
The road starts on the A3002 just south of Brentford station. It heads north along Windmill Road over the railway line and soon reaches the A4, which is crossed at traffic lights. The A4 is dual here, with the elevated M4 supported over the central reservation. As the B452 starts to the south of the A4 the road is out-of-zone, which poses the question as to whether the southern end of the road ever had an in-zone number.
We continue north of the A4 and soon a mini-roundabout is reached. We turn right here and soon reach a T-junction where we TOTSO left (right is the B4491). Heading north once again the road goes over the Piccadilly Line by Northfields station and then winds along Northfields Avenue to reach the A4020 at traffic lights. On the far side is another station, West Ealing, on the Great Western Main Line. Shortly afterwards we cross a roundabout and then run alongside Cleveland Park to a further roundabout on the B455, where the road ends.
