The A4 continues along Talgarth Road past the London Academy of Music and Dramatic Art.
The road becomes elevated at the Hammersmith Flyover and heads towards Heathrow Airport along the Great West Road, passing Hammersmith's two churches of St Paul and St Peter.
At this point the road is close to the River Thames.

The road enters Chiswick and the Borough of Hounslow, passing Fuller's Brewery.
After Hogarth Roundabout, the road passes Hogarth's House and is called Hogarth Lane, then Ellesmere Road and Cedars Road.
It becomes the Great West Road again just a few yards short of the start of Chiswick Flyover, which is junction 1 of the M4.
Gunnersbury's Russian Orthodox Cathedral is clearly visible on the right.

The road then passes the Glaxo-Smith Kline premises in Brentford where it follows underneath its successor the M4 as far as the bridge over the River Brent.
 The stretch between Chiswick's western border to Syon Lane (Gillette Corner) is known as the Golden Mile with some notable Art Deco factories.
The road remains as the Great West Road through Osterley and Hounslow where it splits with the A30, which is known as the Great South West Road.
Between the two world wars, the Great West Road was built as a bypass to relieve traffic congestion in Brentford and Hounslow.

After the A30, the A4 changes its name to Bath Road, enters Cranford, and crosses the River Crane into the Borough of Hillingdon.
It then passes along the northern boundary of Heathrow Airport, before leaving the London suburbs over the M25 towards the west.
