North Sea The nearest passenger ferries to Hook of Holland actually depart from Harwich, across the Orwell south of Felixstowe. That ferry has 2 daily departures, one is a day crossing, the other a night crossing, both taking about 7–8 hours. It carries foot (train) passengers and cyclists as well as cars, buses, caravans and freight lorries. The ferry has bunks and rooms available to accommodate those on either crossing. Tickets for Dutch rail travel can be purchased on the ship.<ref>For more information see: StenaLineTemplate:Webarchive or London to the NetherlandsThe Man in Seat Sixty-One</ref> Ferries departing from Felixstowe carry freight only.
On mainland Europe, the E30 terminates at Hoek-van-Holland where a ferry is required to cross the North Sea to Felixstowe, United Kingdom. The Port of Felixstowe is a major UK freight port with limited passenger operations present. In 2014, Felixstowe handled 28.1 megatonnes of freight, demonstrating the importance of the port within UK import and export sectors, as well as within sectors responsible for the development of UK road infrastructure concerning the E30.<ref name=":1">{{#invoke:citation/CS1|citation

Ipswich - The Port of Ipswich handles approximately 2,000,000 tonnes of freight each year according to the Association of British Ports - Ipswich is the UK's largest export port.<ref>{{#invoke:citation/CS1|citation
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.<ref>Template:Cite news</ref> This is because the destinations along the M4 route have become "hubs for the UK bases of major global high-tech companies."<ref>Template:Cite news</ref>
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.
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.<ref name=":2">{{#invoke:citation/CS1|citation

The E30 serves several major industrial destinations in Wales which are largely an extension of "Britain's Science Corridor". These include:
Chepstow is home to several scientific research centres, for example, CreoMedical, a firm which develops medical technologies for hospitals across the UK.<ref>Template:Cite news</ref>
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 £1.5 billion to the economy.<ref>{{#invoke:citation/CS1|citation

This can be shown in the closure of South Wales' last deep mine in 1994.<ref>{{#invoke:citation/CS1|citation

In November 2016, Brexit supporter David Rowlands AM (UKIP) argued that the Welsh Government should use trans-European Highways Access funds to maintain the M4 following the UK's departure from the EU. This would be in addition to those which Wales have already received to develop the M4 motorway in Wales. He justified his viewpoint by claiming that a large proportion of all Irish exports, both to the UK and the EU, pass along this route.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
