A2

A2 is a major Trunk road in Southeast England, connecting the City of London to the Port of Dover. It follows the historic course of the Roman road Watling Street and serves as a critical transport artery for freight and passenger traffic to continental Europe. The road has been progressively upgraded, with significant sections now forming part of the M2 motorway and the similarly designated route in Northern Ireland.

History

The origins of the A2 lie in the ancient Watling Street, a vital Roman thoroughfare linking the ports of Richborough and Dover to Londinium and onward to Wroxeter. Following the Norman Conquest, the route remained a principal highway, with sections like the Old Kent Road becoming infamous in Charles Dickens's literature. The modern numbering was established in the Ministry of Transport's 1922 road numbering scheme, designating it as one of the original single-digit A-roads radiating from London. Major 20th-century developments included the construction of the Dartford Tunnel in 1963 and the bypassing of towns like Canterbury and Rochester. The road's importance was further cemented by its role in the Strategic road network and its connections to Channel Tunnel traffic.

Description

The A2 begins at the historic New Cross in Lewisham, near the Greenwich meridian. Its initial urban section passes through Bexley and Dartford, crossing the River Thames via the Queen Elizabeth II Bridge at the Dartford Crossing. Beyond Gravesend, the route becomes a dual carriageway, skirting the North Downs and passing the Bluewater Shopping Centre. It traverses the Kent countryside, intersecting with the M20 motorway near Maidstone and the M2 motorway near Strood. The final stretch runs through the White Cliffs of Dover area before terminating at the Eastern Docks in Dover, adjacent to Dover Castle.

Applications

As a primary route to the English Channel ports, the A2 is indispensable for European freight, linking the M25 motorway to ferry services operated by companies like P&O Ferries and DFDS Seaways. It provides vital access for commuters to London from Kent towns such as Gillingham and Sittingbourne. The road also supports tourism, facilitating travel to historic sites including Canterbury Cathedral, a UNESCO World Heritage Site, and Leeds Castle. Furthermore, it serves as a key diversion route when the M20 motorway is closed for Operation Brock or incidents at the Eurotunnel terminal in Folkestone.

Variants

Several notable variants and related routes exist. The A2 road (Northern Ireland) runs from Belfast to Derry, passing through Antrim and Toome. In London, the A200 road follows a parallel course to the original A2 alignment through Deptford. The A102 road was a designation for the southern approach to the Blackwall Tunnel. The most significant variant is the M2 motorway, which supersedes the A2 between Brenley Corner and Strood, relieving congestion. Other spurs include the A207 road in Dartford and the A205 road in South London.
