Hanger Lane Gyratory is a large traffic gyratory on the boundary between Ealing, Harrow, and Hounslow in West London, England. The junction connects the A40 road, the A406, and local roads near Hanger Lane tube station on the Central line (London Underground). It is noted in urban planning and transport discussions for its scale, complexity, and impact on local communities such as Perivale and Alperton.
The gyratory was developed during post-war road expansion linked to projects like the British motorway network and the reconstruction programmes influenced by figures such as Sir Patrick Abercrombie and organisations like the London County Council. Early designs emerged in the 1960s when authorities including Middlesex County Council and later Greater London Council implemented high-capacity junctions to accommodate traffic from routes to Oxford Street and the M25 motorway. Subsequent decades saw interventions by Transport for London and planning appeals involving stakeholders such as Ealing Borough Council and local residents' associations influenced by national policies like the Town and Country Planning Act 1947.
The gyratory’s geometry reflects mid-20th-century engineering approaches found in junctions influenced by studies from Ministry of Transport consultants and precedents like the Hammersmith Flyover. Its carriageways form a multi-lane one-way loop with signalised crossings and slip roads connecting to the A40(M) approaches and radial routes toward Central London, West London and approaches to Heathrow Airport. Structural elements include piled viaducts, retaining walls surveyed with standards from British Standards Institution documents and drainage tied into the River Brent catchment. Designers debated multimodal integration with references to schemes promoted by think tanks including the Transport Research Laboratory.
Traffic flow at the gyratory has been the subject of analysis by Transport for London, academic departments such as Imperial College London transport research groups, and safety audits by firms linked to the Highways Agency. Peak-hour congestion affects routes toward Marylebone and Notting Hill, with collision records reviewed by the Metropolitan Police Service road policing unit and Road Safety GB initiatives. Countermeasures trialled have included signal retiming based on algorithms used in projects by Siemens and Cubic Transportation Systems and coordination with regional traffic control centres operated by TfL.
The junction interfaces with the London Underground via Hanger Lane tube station on the Central line (London Underground), and with bus services operated by private contractors under contracts with Transport for London. Routes serving the gyratory connect to hubs such as Ealing Broadway station, Wembley Central station, and termini like Shepherd's Bush. Coordination with rail operators including Network Rail and passenger information systems by Arriva London and Metroline have been central to multimodal interchange planning, including proposed links to projects promoted by Crossrail advocates.
Pedestrian crossings and segregated footways around the gyratory have been modified following campaigns by groups such as Sustrans and London Cycling Campaign. Cycle provision has been criticised in reports involving Cycle Logistics research and advocacy by organisations like Transport for Greater Manchester in comparative studies. Improvements have included signal-controlled crossings, tactile paving to meet Equality Act 2010 accessibility standards, and proposals for segregated lanes consistent with guidance from DfT and design manuals endorsed by Local Government Association.
Various redevelopment proposals have involved borough planning teams from London Borough of Ealing and consultants from practices linked to the Royal Institute of British Architects. Options have ranged from partial grade separation to wholesale redesigns inspired by schemes such as the Alaskan Way Viaduct replacement and urban regeneration projects like King's Cross Central. Funding discussions have involved bodies including Homes England and transport investment instruments referenced in National Infrastructure Commission reports. Public consultations conducted under rules of the Localism Act 2011 gathered responses from community groups and developers proposing mixed-use schemes near corridors toward Park Royal.
The gyratory has appeared in reportage by national outlets including BBC News, The Guardian, and The Times in features on urban congestion and London's road heritage. It is noted in travel writing by authors associated with Time Out and in photo essays distributed by agencies such as Getty Images documenting Brentford and Ealing transport landscapes. Film and television productions shooting on location in West London occasionally reference the junction in logistical planning coordinated with Film London and the Metropolitan Police Service film unit.
