A2 road
For the expressway in Switzerland, see A2 (Switzerland). For the road in Northern Ireland, see A2 road (Northern Ireland).The
A2 is a major road in the
United Kingdom, connecting
London with the
English Channel port of
Dover in
Kent. That route has always been of importance as a connection between
Continental Europe and the major part of the
British Isles.

The modern A2 crossing the Medway at Rochester near the Roman and Celt crossings |
The original A2 roughly followed the route of a
Celtic
ancient trackway which the Romans later paved and identified as Inter III on the
Antonine Itinerary. The Anglo-Saxons named it
Wæcelinga Stræt which developed into the modern
Watling Street. It was one of the most important Roman roads in Britain, since it linked London with
Canterbury , and from there to three Channel ports:
Richborough (
Rutupiae); Dover (
Dubris) and
Lympne (
Lemanis). The road had river crossings at
Rochester over the
River Medway;
Dartford (
River Darent) and
Crayford (
River Cray). It continued in use long after the Romans departed in the 5th century.
By the 17th century the road, like most roads in Britain, had fallen into disrepair, although the bridge at Rochester remained in good condition, since it was controlled by the Bridge Wardens.
Turnpike Acts began to be passed by
Parliament, as a result of which such roads were opened piecemeal: the section of what is now the A2 between
Gravesend and Rochester was turnpiked in 1712; that between
Chatham and Canterbury in 1730. The road from there to Dover was not turnpiked until early in the 19th century, by which time it had become known as the Great Dover Road.
In the 1920s, when British roads were allocated numbers, the A2 became the principal road in the south-eastern section of Britain. Its original alignment roughly followed a mix of the ancient Celtic route and the turnpike road to Dover. The Roman alignment, however, is not easy to identify and much of the original A2 does not exactly follow what is known of the Roman route (the straightness of many long stretches is misleading). However, a section of the modern A2 from Rochester to the Roman settlement of
Vagniacae, modern
Springhead, is believed to roughly follow the Roman route.
Borough to Shooter's Hill
The A2 starts at
Borough in SE London, at a junction with the
A3. The remains of a small
Roman temple was recently excavated at Tabard Square. The A2 at this point is named Great Dover Street, and is the only part of the A2 within the
congestion charging zone. At the end of the road, it meets the
London Inner Ring Road and becomes a primary route. The A2 heads along
Old Kent Road towards
New Cross, where the
A20 breaks away. The A2 continues east through
Deptford and
Blackheath until it arrives at the
Shooter's Hill Interchange with the A102 near
Greenwich. A section of the Roman road has been identified running through Greenwich Park on an alignment with Vanbrugh Park.
Shooter's Hill to Three Crutches
At Shooter's Hill, Watling Street and the A2 part company, as Watling Street continues along the
A207. At this point the A2 joins a
dual carriageway, the Rochester Way (the carriageways to the north of this junction being the A102) with a 50mph limit. The western part, the Rochester Way Relief Road, was constructed in the
1980s.
The A2 meets traffic lights at
Kidbrooke, but this is the last set out of London and from here the A2 is a
motorway in all but name, with 3 lanes and a hard shoulder in each direction. The left hand lane is used for local traffic. At
Falconwood, the road becomes the East Rochester Way - this point was once the westbound terminus of the dual carriageway. There are exits for
Bexleyheath,
Bexley and other London surburbs. Motorists should also be aware of the numerous speed cameras along this stretch. Once the A2 enters
Kent, the speed limit increases to the national speed limit (70mph) and the road heads east towards Dartford, bypassing the town to the south. It meets the
M25 at Junction 2, the next junction is with the B255 and
A296 for
Bluewater where Watling Street rejoins the A2. The A2 bypasses Gravesend, becoming four lanes, before merging into the
M2 at Three Crutches Interchange.
Three Crutches to Brenley Corner
The A2 reverts to a non-primary single carriageway road at this point. Leaving the M2 to bypass the Medway Towns, the A2 heads into them. It enters
Strood before crossing the
River Medway into
Rochester. The A2 bypasses the old High Street, heading instead alongside the railway lines. It heads east into
Chatham where it meets the
A230 and
A231 by way of a one way ring road. The A2 heads to the south of
Gillingham, where the
A289 Medway Northern Bypass joins it. The
A278 departs from the A2 to head south to meet the M2, whereas the A2 goes through
Rainham and
Newington before entering green country for the first time since Three Crutches.
The road meets the
A249, now dualled, to the west of
Sittingbourne, before going through the town itself (bypassing the now-pedestrianised High Street, as it does in Rochester and Chatham). Leaving Sittingbourne, the A2 continues east in almost a straight line, for it is still along the alignment of Watling Street at this point. It arrives at Faversham, but doesn't (and never has done) go through the town, preferring to almost bypass it to the south. A mile later, it arrives at Brenley Corner, junction 7 of the M2.
Brenley Corner to Dover Docks
At Brenley Corner, the A2 once again becomes a primary dual carriageway. Straight after the interchange,
Dunkirk and
Boughton are bypassed as the A2 continues towards Canterbury and Dover. Formerly it went through Canterbury city centre, this has now been bypassed and the original route is now called the
A2050. It breaks off from the A2 at
Harbledown - just after Gate Services - taking all Canterbury traffic with it. At Wincheap, the
A28 meets the A2, although only westbound traffic can exit the A2 at this point. The A2050 rejoins the A2 at
Bridge.
Traffic for the
Channel Tunnel and
Folkestone leaves at the junction with the
A260, and shortly after this junction the A2 loses its dual carriageway status, regains it, and loses it again within a few miles. Now single carriageway, the A2 forms the Dover bypass. It meets the
A256 for
Sandwich and
Ramsgate at a briefly-dualled section, before reverting to single carriageway for the final time. The A2 breaks through the cliffs above Dover Docks before turning 180 degrees and "touching down" on land again at the entrance to the Eastern Docks, where both it and the
A20 terminate.
