The Colne Valley Viaduct is a bridge, under construction as of 2023, which will carry the High Speed 2 railway over the Colne Valley Regional Park and the Grand Union Canal, in Hillingdon, west London. When completed, its length of 3.4 kilometres (2.1 mi) and a weight of 116,000 tonnes will make it the largest railway bridge in the UK. It is one of the largest single civil engineering works of HS2 Phase 1.A contract for the section of the railway pertaining to the viaduct was awarded during 2017 and the design concept was released to the public on 19 January 2018. Preparatory work commenced shortly thereafter, including a compulsory land purchase and the establishment of temporary facilities, including a factory, onsite. Construction of the viaduct commenced during March 2021 with completion of the main deck due to occur during 2024 with full completion expected for May 2025.

Harefield Road was a proposed London Underground station on the western branch of the Central line beyond its current terminus at West Ruislip. Under the London Passenger Transport Board's 1935–1940 New Works programme, the station would have been built alongside the existing Great Western and Great Central Joint Railway (GW&GCJR) line between West Ruislip and Denham as the penultimate station on the Central line's extension from North Acton.Like many other new stations built by London Underground in the outskirts of the capital, the construction of the station was intended to stimulate new housing developments in what was a rural part of Middlesex. Works on the extension were postponed during World War II and, after the war, green belt legislation was introduced to limit the expansion of urban areas. The area beyond West Ruislip fell within the designated Metropolitan Green Belt, and, as the intended housing developments were no longer allowed, the extension beyond West Ruislip was cancelled.
