The European route E 01 is a series of roads in Europe, part of the United Nations International E-road network, running from Larne, United Kingdom to Seville, Spain. There is a sea crossing between Rosslare Harbour, in the Republic of Ireland, and Ferrol, but no ferry service. The road also passes through Portugal – past the city of Porto, through the capital, Lisbon, and then south to the Algarve, passing Faro before reaching the Spanish border west of Huelva.

United Kingdom

As with all E-roads in the United Kingdom, the E 01 is not signed. It begins in Larne, County Antrim as the A8. A short section of the A8 at Newtownabbey is under motorway regulations and is signed as the A8(M) motorway. This motorway joins the much longer M2 motorway to Belfast. At Belfast, the road becomes the A12 Westlink, a dual carriageway which links to the M1 motorway. The A1 leaves the motorway near Lisburn and continues south as a dual carriageway. This takes the road over the border to the Republic of Ireland.

Republic of Ireland

E01 in County Wexford, Republic of Ireland.

The dual carriageway continues in the Republic of Ireland as the N1, which from Ballymascanlon in County Louth onwards is under motorway regulations and signed as the M1 motorway. The road follows the M1 south to Dublin, where, in the northern suburbs, it meets Dublin's ring road, the M50 motorway. It follows the M50 through the outer suburbs of Dublin until it meets the short M11 motorway near Shankill. The M11 continues as a dual carriageway, the N11, south of Bray in County Wicklow. This section passes through the Glen of the Downs Nature Reserve. Apart from a section of standard highway (single carriageway road) between Rathnew and Arklow in County Wicklow, the road is dual carriageway or motorway to south of Gorey in County Wexford. Following this, the remainder of the route in Ireland is single carriageway and passes through several towns and villages. The N11 continues to Wexford, where at a junction outside the town it meets the N25 road from Cork. The route follows the N25 to its final destination in Ireland of Rosslare Europort.

All remaining sections of the N11 (and therefore E01) outside of Dublin are due to be replaced by motorways or dual carriageways.

Spain

E01 near Vigo, Spain.

The E 01 has two sections in Spain. The northern section is between Ferrol and Tui at the Portuguese border. It follows the motorway AP-9, aka The Atlantic Axis, which connects the Galician cities of Ferrol, A Coruña, Santiago de Compostela, Pontevedra and Vigo, continuing south towards Portugal. The border is at the river Minho, at the city of Tui.

Portugal

E01 passing at Ponte do Freixo, Porto.

In Portugal, the route is composed of the following sections, always as a motorway (called auto-estrada in Portuguese):

• A3: Valença (border) - Braga - Porto
• A1: Porto - Coimbra - Lisbon
• A2: Lisbon - Albufeira
• A22: Albufeira - Castro Marim (border)

In the section Aveiro Norte - Lisbon of the A1, the E01 follows the same route as the E80. In that section the E80 signage prevails over the E01 signage, this last rarely appearing.

Spain

The second Spanish section is between Ayamonte at the Portuguese border and Sevilla. It follows the motorway A-49, and passes near the city of Huelva. The border is at the Guadiana river.
