The M11 motorway is a 55-mile (88.5 km) motorway that runs north from the North Circular Road (A406) in South Woodford in northeast London to the A14, northwest of Cambridge, England. Originally proposed as early as 1915, various plans were considered throughout the 1960s, with final construction being undertaken from 1975–80. The motorway was opened in stages, with the first stage (between Junctions 7 and 8) opening in June 1975, and the completed motorway becoming fully operational in February 1980. Running from South Woodford to Girton, the motorway provides direct access to Harlow, a large new town, as well as the city of Cambridge and since 2002, the motorway has greatly improved access to London Stansted Airport, the fourth busiest airport in the United Kingdom.
The M11 starts in South Woodford in northeast London at Junction 4, with the North Circular (A406), it then heads NNE, passing east of Loughton and Theydon Bois as well as Epping Forest, meeting the M25 motorway at Junction 6, and then veering approximately north, passing to the east of Harlow. The M11 gives access to Bishop's Stortford and the motorway's only service station via Junction 8. This is followed immediately by the recently constructed Junction 8A, which provides a free-flow link to the improved A120 that links to Stansted Airport. The M11 then traverses part of Cambridgeshire, meeting a spur for the A11 at Junction 9, and then finally ends at Junction 14, the busy Girton Interchange, with the road continuing through the junction and becoming the A14, which continues the route on to Huntingdon and the north.
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 Stockholm 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.
The N11 road is a national primary road in Ireland, running for 135 km (84 mi) along the east side of Ireland from Dublin to Wexford. It passes close to Bray, Greystones, Wicklow, Arklow and Gorey and also passes through Enniscorthy, amongst others. Beyond Wexford, the route continues to Rosslare as the N25. The road forms part of European route E01. As of 2015 the N11/M11 is of dual carriageway or motorway standard from Dublin as far as Gorey in County Wexford.
The road is a busy commuter route, being the only dual carriageway passing through the south eastern suburbs of Dublin, as well as close to the many commuter towns along the east coast as far south as Gorey. Summer Friday and Sunday evenings also see very heavy traffic as Dubliners decamp to, and return from, their many holiday home locations along the Co. Wicklow and Co. Wexford coastlines.
