Introduction
The photograph on this page of Dollis Brook Viaduct by Martin Addison as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

The viaduct carries Mill Hill East trains 18m (60ft) above Dollis Road (though I have seen it quoted as being 80ft tall and it looks all of that from below). It is the highest point above ground level on the London Underground network, info from Transport for London website. It was constructed between 1863 and 1867.
