28. London The E30 avoids travelling through the centre of London by using the M25 to the north of London between junctions 28 and 15. Major connections: M11 A10 A1(M) A405 M1 A41 M40 M4 - M25 junction 15 M4 Corridor: London - Bristol To the west of London, the E30 uses the M4 motorway to South Wales. The destinations along this route are linked as part of the M4 corridor, named "Britain's Science Corridor" by the New York Times upon its inception in 1983. This is because the destinations along the M4 route have become "hubs for the UK bases of major global high-tech companies." The London to Bristol route largely follows that of the Great Western Main Line, which serves as a major infrastructural passenger and freight route between some of the destinations along this section of the E30. Major destinations along this route include: London Heathrow Airport Slough Maidenhead Reading Newbury Swindon Bath Bristol M4 Corridor: Bristol - Pont Abraham West of Bristol, the E30 crosses the River Severn over the Second Severn Crossing. The Severn Bridge is used as an alternative to and from Chepstow, which is not directly accessible from the E30. In Wales, the roads which carry the E30 are managed by the South Wales Trunk Road Agent on behalf of the Welsh Assembly Government. The E30 serves several major industrial destinations in Wales which are largely an extension of "Britain's Science Corridor". These include: Chepstow Newport Cardiff Bridgend Port Talbot Swansea Llanelli Chepstow is home to several scientific research centres, for example, CreoMedical, a firm which develops medical technologies for hospitals across the UK. Newport, Cardiff, Port Talbot, Swansea and Llanelli are coastal destinations with sea links. ABP maintains a presence at some of these destinations (not Llanelli, additionally at Barry), and handles over 12 million tonnes of freight each year, contributing over £1.5billion to the economy. This has been developed thanks to the historic development of infrastructure relating to the South Wales Valleys mining industry in the 20th Century, which has since declined in recent decades with the rising imports of foreign oil. This can be shown in the closure of South Wales' last deep mine in 1994. Cardiff is the capital city of Wales and serves as Wales centre for governance, business and culture. The devolved government of Wales is housed in Cardiff Bay. In November 2016, Brexit supporter David Rowlands
