London Heathrow Airport is Europe's busiest airport in terms of passenger traffic and the Dublin-London route is the busiest air route in Europe. The English Channel and the southern North Sea are the busiest seaways in the world. The Channel Tunnel, opened in 1994, links Great Britain to France and is the second-longest rail tunnel in the world.

The idea of building a tunnel under the Irish Sea has been raised since 1895, when it was first investigated. Several potential Irish Sea tunnel projects have been proposed, most recently the Tusker Tunnel between the ports of Rosslare and Fishguard proposed by The Institute of Engineers of Ireland in 2004. A rail tunnel was proposed in 1997 on a different route, between Dublin and Holyhead, by British engineering firm Symonds. Either tunnel, at 80 km (50 mi), would be by far the longest in the world, and would cost an estimated €20 billion. A proposal in 2007, estimated the cost of building a bridge from County Antrim in Northern Ireland to Galloway in Scotland at £3.5bn (€5bn).
