English: Harrow on the Hill: Waldron Road Waldron Road has to be one of the narrowest two-way through roads in the country, which coupled with the steepness of the hill makes driving a little difficult. The distance from kerb to kerb is only about 4 metres. The terraced houses on the right are original, those on the left quite modern (they are not shown on the Ordnance Survey map of 1935 for example), but built in the style of the originals. 1654389 is to the left.
