Beyond Uxbridge and the Western Avenue, Harefield Road leads ultimately to the village mentioned in its name.
Harefield Road – in its section beyond the A40 – was a proposed Underground station on the branch of the Central line beyond its West Ruislip terminus set up due to the 1935–1940 New Works programme.
The station would have been built alongside the existing Great Western tracks between West Ruislip and Denham as the penultimate station on the Central line extension.
The construction of the station was intended to stimulate new housing development but, after the Second World War, green belt legislation was introduce. The area beyond West Ruislip fell within this area and so the extension beyond West Ruislip was cancelled.
