The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993.

The M4 motorway is a 55-kilometre (34 mi) [1] series of partially tolled dual carriageway motorways in Sydney designated as route M4. The M4 designation is part of the wider A4 and M4 route designation, the M4 runs parallel and/or below ground to Great Western Highway, Parramatta Road and City West Link, which are part of route A44.

The M4 is, effectively, the Great Western motorway, doing exactly that job but for the modern era. From suburban London it follows the Thames Valley past Slough, Maidenhead and Reading - home, today, of Britain's technology companies, and a place that has earned the M4 the nickname the "silicon highway".

The A4, A44 and M4 are a collection of arterial routes in Sydney, New South Wales that connect the Inner West of Sydney with the outer western suburbs.
