M4 motorway M4 motorway The M4, a motorway in the United Kingdom running from west London to southwest Wales, was originally referred to as the London-South Wales Motorway. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was completed in 1993. The Second Severn Crossing officially renamed the Prince of Wales Bridge, was inaugurated on 5 June 1996 by HRH The Prince of Wales and the M4 was rerouted. Apart from its two spursthe A48(M) and the M48the M4 is the only motorway in Wales. From London to Bristol, the M4 runs close to the
M4 cycleway down underneath the M4, above the Duck Creek and the A'Becketts Creek. The path runs through the middle of the M4 cement columns which forms a scenic reminder, albeit suburban, of the functionality of the path. The path continues to follow the cement colonnade of the M4. On either side of the path are access points from Harris Park. Near the junction of Parramatta Road, Church Street, and Woodville Road, where the M$ passes over the junction, the cycleway provides various spur options: the north to Parramatta central business district via High, Wigram, or Railway Streets; and to the south
