(Redirected from Great West Road)
The 'A4' is a major road in
England, portions of which are known as the 'Great West Road' and 'Bath Road'. It runs from
London to
Avonmouth, near
Bristol. Historically the road is the main route from London to the west of England, and has formed the main western artery from
London. Much of the route has been paralleled by the
M4 motorway.
Starting at
Holborn Circus at a junction with the A40 in the
City of London, it runs west into
Westminster through
Fleet Street, the
Strand,
Trafalgar Square,
Haymarket,
Pall Mall,
Piccadilly Circus, past
Green Park to
Hyde Park Corner. At this point it leaves the
congestion charging zone and continues through
Knightsbridge,
South Kensington,
Hammersmith and
Chiswick. The road runs past some of London's most famous buildings and institutions, including the
Royal Courts of Justice,
King's College London,
London School of Economics,
St Martin-in-the-Fields Church,
Bush House,
Nelson's Column, the
National Gallery,
Royal Academy of Arts,
Ritz Hotel,
Harrods, the
Victoria and Albert and
Natural History Museums and
Heathrow Airport. The road is one of London's main western arteries - along with the
A40 Westway towards Oxford - , forking into the old A4, M4 motorway,
A316 and
A30 in the suburbs.
Outside London the road runs through
Slough,
Maidenhead,
Reading (past
Cemetery Junction),
Newbury,
Hungerford,
Marlborough,
Calne,
Chippenham,
Corsham,
Bath and Bristol. In Bristol the road forms an inner city
ring road and runs through the
Avon Gorge, terminating at the
M5 motorway and Avonmouth docks. In the original 1922 road numbering list, the section from Bath to Avonmouth was classified as the
A36, but section became part of the A4 very early on.
[1]
The road was formerly classified as a
trunk road, but since the
1960s the M4 motorway has relieved the road of long distance and freight journeys. Sections in Bath, Bristol and central London remain designated as trunk road, and traffic is mostly segregated on dual-carriageway on these sections.
The A4 is actually a combination of old roads and new. The Bath Road, the original road from London to the west, ran through Hammersmith,
Turnham Green,
Brentford to
Hounslow. Here the Staines Road forked off left at the Bell Corner, and the Bath Road continued onwards to
Colnbrook and Maidenhead. Between the wars the Great West Road was built as a bypass to relieve traffic congestion in Brentford and Hounslow. This ran across farmland from what is now the Chiswick Roundabout, rejoining the Bath Road where the Traveller's Friend pub near
Cranford was once situated; the building still exists, but is now a McDonalds Fast Food Restaurant. A bypass for Colnbrook followed after the Second World War, built across farmland between Harmondsworth and the outskirts of Langley. These bypasses now constitute part of the A4, and the older roads have been renumbered. The London end of the road became Britain's first
dual carriageway when it was opened in 1925 by King George V
[2].
Continued rising traffic levels forced the construction in the early sixties of the first part of the M4 - between the Chiswick Roundabout and Maidenhead Thicket roundabout - to wholly bypass the A4, although the roads actually cross three times; first at the Chiswick flyover (M4 J1), next just east of Slough (M4 J5) and finally to the west of Reading (M4 J12).

Trivia
The A4 appeared in the 1996 film ''
Trainspotting'' when the main characters (Renton and Sickboy) moved into a flat on the Talgarth Road (the stretch of the A4 between
West Kensington and
Hammersmith). The film contains a specific shot of the junction of Talgarth Road with North End Road.
