The Northolt tunnel will carry the High Speed 2 (HS2) railway line under West London, England. The twin-bore tunnels will run between Old Oak Common railway station and Ruislip. Plans for the construction of a tunnel were first unveiled in early 2013; it was hailed as being less disruptive and quicker to construct that a surface-based alignment. An option for the tunnel's extension along the Colne Valley to replace the proposed Colne Valley Viaduct was studied but rejected as unnecessarily costly during 2015. Extensive ground surveys along the intended route were conducted during the 2010s in advance of construction work. During April 2020, it was announced that a contract worth approximately £3.3 billion had been awarded to a joint venture company, Skanska Costain Strabag, for the tunnel's construction.
