# A35 road

The A35 is a major road in southern England, connecting Honiton in Devon and Southampton in Hampshire. It is a trunk road for some of its length. Most of its route passes through Dorset and the New Forest. It originally connected Exeter and Southampton, the original A35 ran along what is now the A3052 joining the present road at Charmouth.

## Route

Beginning in Honiton at the eastern junction with the A30 road, the A35 travels in a roughly south-easterly direction past Axminster, Charmouth and Bridport. After Bridport, there is a 2-mile (3.2 km) section of dual carriageway, before it reaches its bypass around Dorchester. After Dorchester, there are approximately 8 miles (13 km) of dual carriageway, including the Puddletown bypass, until it reaches its roundabout with the A31 road at Bere Regis. Continuing roughly south-easterly still, it becomes dual carriageway again near Upton, before returning to a single carriageway through Poole and Bournemouth, apart from a small section of dual carriageway on Wessex Way. On reaching Christchurch, there is a dual-carriageway bypass. It then heads in a north-easterly direction through the New Forest, passing through Lyndhurst where it meets the A337 road (to Lymington). It continues through Ashurst and Totton, meeting the A36 road and M271 motorway at grade separated junctions. It then turns north-east, acting as the western part of Southampton's ring road, with the A27 road making up the eastern part. It terminates at Swaythling, on the northern outskirts of Southampton.

## History
### 1922 - Road classification

The road number was created with the 1922 classification of roads in the United Kingdom. At that time its western terminus was on the then A30 in Heavitree, Exeter. In 1966 the section from Charmouth to Exeter was de-trunked and renumbered to A3052, with the A35 directed over the former A373 to Honiton, terminating at the then-new A30 Honiton Bypass. This added the narrow 220-foot (67 m) long Charmouth Tunnel to the route, built in 1832 to avoid the summit of Thistle Hill.

### 1987/88 - Building of Dorchester and Bridport Bypasses

The A35 is a main route along England's south coast, and was congested. To help solve the congestion, sections of the A35 were upgraded between Honiton and Poole. In 1969 the Ministry of Transport recorded the case for bypasses around Bridport and Dorchester. The 2.4-mile (3.9 km) bypass to the south of Bridport opened almost two decades later in 1987, followed by the 3.7-mile (6.0 km) bypass to the south of Dorchester in 1988.

### 1990/91 - Building of Axminster and Charmouth Village Bypasses

Following the re-routing onto the former A373 road, a major traffic bottleneck was the town of Axminster. A much-desired southern bypass for the town was indefinitely postponed in 1980 by the then Parliamentary Under-Secretary of State for Transport, Kenneth Clarke. The 3.65-kilometre (2.27 mi) project was eventually authorized by Act of Parliament in 1987, with construction beginning in 1990 approximately following the line of a Roman road. Charmouth village was bypassed in 1991, with the Charmouth Tunnel bypassed at the same time. The defunct tunnel was converted into a shooting range in 2010.

### 1999 - Puddletown Bypass

The Puddletown dual carriageway bypass which opened in 1999 (together with the A30 Honiton-Exeter dualling) were financed under a Design, Build, Finance and Operate (DBFO) contract running from 1996 to 2026.

### 2004-2007 - Road straightening between Slepe and Upton

An on-line straightening between Slepe and the Upton bypass was carried out in 2004, and the extension of the 50 miles per hour (80 km/h) speed limit west of Slepe by 1 mile (1.6 km) in 2007.

### Bournemouth Centenary Way diversion

In Bournemouth, it has been diverted around the Sovereign Centre of Boscombe along Centenary Way resulting in a 1.9-mile (3.1 km) concurrency with the A338; much of its former route is now pedestrianised.

## Incidents

In May 2021, a sinkhole opened on the carriageway following emergency repairs to a pothole on the A35 Puddletown bypass near the junction for Troytown. The road was closed to allow remedial works to be carried out.
In October 2021 the edge of the eastbound carriageway collapsed into a field where the A35 ascends an escarpment 1.1 miles (1.8 km) east of Honiton. Due to the complex ground conditions repairs took 8 months to complete with temporary signals controlling single-file traffic for that time.
