E20 shield

The European route E 20 is part of the United Nations International E-road network.

It runs roughly west–east through Ireland, the United Kingdom, Denmark, Sweden, Estonia and finally Russia. The length is 1,880 km (1,170 mi).
The road is not continuous; at three points, a sea crossing is required. Roll-on/roll-off ferries make the crossings from Dublin to Liverpool and from to Tallinn. No vehicle-carrying vessels traverse the North Sea from Kingston-upon-Hull to Esbjerg (as of 2013).

The initial section of the E 20 from Shannon Airport to Dublin via Limerick is approximately 228 km long and is only partially signed, along the M7/N7. The section from Shannon Airport to east of Limerick is mainly dual carriageway, with a short section of motorway as part of the Limerick Southern Ring Road. The Shannon Tunnel, opened on 16 July 2010, completed the bypass of Limerick. The section from Limerick to Naas is motorway (M7), and the final section from Naas to Dublin is dual carriageway (N7). A ferry must be used from Dublin to Liverpool.
