19th century

The modern course of the A303 was designed in the early 19th century as the "New Direct Road" by William Hanning, chief engineer of the Ilminster Turnpike Trust, in order to improve coaching traffic to southwest England. Russells of Exeter began a coach service along it, though they quickly reverted to the older coaching route further south (now part of the A30). Along with engineer

caused coaching services to dry up. Along with many other turnpike routes, the New Direct Road fell into disrepair during the 19th century owing to a lack of funds and available staff. By the turn of the 20th century, it had become little more than a rough track in places, making it difficult to drive on.

, the Government's official mapping body, marked the New Direct Road as a "class I" route anyway. The A303 was created on 1 April 1933 as the "Alternative London – Exeter route" after the Ministry of Transport realised the New Direct Road was still useful as a major road for motor traffic. The route created a long bypass for sections of the A30 that ran south of it. In 1958, the Ministry of Transport upgraded the A303 to

) or to dual carriageway; but none were longer than . Andover and Amesbury were bypassed in 1969, while general improvements to the road, including additional dualling, took place throughout the 1970s. In 1971, the Environment Secretary, Peter Walker announced the entire length of the A303 would be upgraded as part of a new roads programme that would deliver 1,000 new miles of motorway by 1980. New bypasses were build, such as Wyle in July 1975, A bypass of

was opened in 1976; it was (and remains) the only dual carriageway upgrade of the A303 through the Blackdown Hills. The section between Wincanton and Holton opened in stages throughout 1977, costing £3m. By the mid-1980s, the A303 had been extended from its original fork by Micheldever Station, next to the A30, eastwards to meet the M3 motorway, and was a completely uninterrupted dual carriageway westwards as far as Amesbury. A bypass of Ilminster had been planned since 1976, but by 1982 the Transport Secretary David Howell had rejected the original dual carriageway plans, calling them "'a waste of money". The new road was built as single carriageway with 3 lanes, which caused a serious safety hazard leading to several fatal accidents. A bypass of Sparkford was opened on 25 October 1989 by Robert Atkins (politician), while an upgrade to the South Petherton to Ilchester section was opened by

Traffic

Since the 1950s, the A303 has been criticised for being inadequate for the level of traffic along it. In 1959, it was reported that a typical queue for holiday traffic along the road could be as much as . , over of the road west of Amesbury remains single carriageway, interrupted by various sections of dual carriageway. The switches from the latter to the former act as bottlenecks and are major sources of congestion along the route. Upgrading the remaining sections of road is difficult due to environmental concerns; in 1986, an upgrade of the A303 in Hampshire caused public outcry after the work destroyed the remains of an

settlement, and consequently, £100,000 was spent on emergency rescue excavation work. In 2017, Devon County Council criticised the section through the Blackdown Hills, as it did not meet modern traffic standards. Particular criticism was directed at steep gradients, narrow lanes and sharp turns, which contribute to lower average traffic speeds, and a lack of lay-bys and verges that cause significant congestion in the event of a vehicle breakdown. The report also noted that a significant proportion of weekday traffic was on business (37%, while the typical figure was 7%), but with a much larger traffic flow on weekends.

A Road Investment Strategy published by the UK government in 2014 committed to upgrading all the remaining single-carriageway sections of the A303 as far as Ilminster. Highways England have made numerous proposals to improve the road, and in 2016 it was identified under several Nationally Significant Infrastructure Projects.


Future

The most controversial upgrade of the A303 has been improvement to the road through the

A public enquiry into whether the plans were adequate was announced; it concluded that they were, despite protests from charities and landowners that the tunnel should be longer. Two years later, it was announced that there was to be a review of the options for Stonehenge, starting in January 2006, as costs had doubled. The government cancelled the whole scheme at the end of 2007 owing to excessive environmental constraints. In 2016, the Stonehenge tunnel was revived by the Government, who awarded a £17.5m design contract to build a tunnel. Local residents were pleased with the news, but a survey suggested 90% still preferred a diversion away from the stones instead. The plan was finalised the following year as part of a £2 billion programme. Transport Secretary

The village of Winterbourne Stoke is immediately west of the World Heritage Site, and proposals to upgrade the A303 in this area have generally provided a bypass for it. There have also been proposals to build a bypass as a standalone project, without requiring the improvements around Stonehenge.

to reduce traffic west of Ilminster. The scheme was the subject of a public consultation in March 2007, and incorporated plans to widen the Ilminster bypass from South Petherton to a dual two-lane road. The plans were shelved in 2009 when it was concluded that the dualling could not be funded from the Regional Funding Allocation for the South West. In 2016, the plans were revived by Highways England, with a final decision expected to be announced the following year. In 2019, the preferred route of the A358 upgrade was revealed, and in 2020 the government confirmed funding for the A358 scheme and dualling of the A303 between Sparkford and Podimore. The scheme was cancelled in October 2024 by the new Labour government.


Other schemes

A number of other schemes for the remaining below-standard parts of the A303 were considered in the 1990s, including improvements west of Ilminster towards Marsh, and the single-carriageway section around Yeovilton. These proposals were all cancelled in 1998. The schemes were later remitted to the London to South West and South Wales Multi-Modal Study (SWARMMS), and the conclusion of the report was that all of the schemes east of Ilminster should go ahead; and to avoid building a dual carriageway through the Blackdown Hills the A358 should be upgraded to the M5 at Taunton. In 2009, none were considered to be regional priorities, so no other improvements were likely to be funded in the short term. In 2016,
