Arnos Park Viaduct

Arnos Park Viaduct is a railway viaduct in the London Borough of Enfield that stretches across 34 arches between Arnos Grove and Southgate stations. The structure carries Piccadilly line trains over Pymmes Brook valley while spanning roads including Waterfall Road and Hampden Way.

The viaduct was built in 1932 and opened in 1933 as an essential part of the Piccadilly line extension from Finsbury Park to Cockfosters. This expansion significantly changed how north London was connected by rail.

The structure connects transportation infrastructure with nearby Arnos Park, creating a place where trains pass over green spaces. You can see how the viaduct blends into the surrounding landscape as you walk through the area.

The best view of the viaduct comes from below as you walk under the arches or from nearby paths on the ground. During winter and rain, the ground beneath the structure can become wet and slippery, so wear suitable footwear.

Each of the 34 brick arches received individual numbering, an unusual detail for a structure of this kind. These numeric markings still help with maintenance and documentation of the structure today.
