Wellhead Valley, Westbury & the A36/A350 Corridor

Discover the landscape, history and ongoing campaigns to protect the Wellhead Valley, the Westbury escarpment and the wider Wiltshire countryside from damaging road schemes and urban sprawl.


1. Welcome

The Wellhead Valley and the countryside around Westbury form one of the most distinctive landscapes in West Wiltshire. Framed by the dramatic chalk escarpment and the iconic Westbury White Horse, this area combines rich natural habitats, historic routes and working farmland.

Yet for decades it has also been the focus of repeated road-building plans, most famously the A350 Westbury Bypass proposals. These schemes have raised fundamental questions about how we move around rural England, how we plan our towns, and how we protect the landscapes that define our sense of place.

This site brings together the story of that struggle: the campaigns, the public inquiries, the evolving environmental policy debates, and the search for better, low‑impact transport and planning solutions along the A36/A350 corridor.


2. About this blog

2.1 Purpose

This blog will focus on:

The aim is not only to document what has happened, but to ask what should happen next if we want a future that supports sustainable transport, clean air and a thriving rural landscape.

2.2 Who this site is for

This site is aimed at:


3. The Wellhead Valley & the Westbury Escarpment

3.1 A distinctive corner of rural England

The Wellhead Valley lies just south of Westbury, below the striking chalk scarp crowned by the Westbury White Horse. It is a patchwork of pasture, small fields, hedgerows, streams and footpaths, framed by the dramatic slope of the escarpment and open skies.

Key characteristics of the area include:

This is not a wilderness. It is a working countryside shaped by centuries of farming, quarrying, settlement and movement. But it remains a remarkably tranquil pocket of landscape on the edge of a growing town.

3.2 Why this landscape matters

The Wellhead Valley and Westbury escarpment matter because they offer:

They also matter because they sit at a strategic planning frontier: where road planners, developers, local authorities and communities have repeatedly disagreed about what should happen to this land.


4. The A350 Westbury Bypass Story

4.1 Why the bypass was proposed

For many years the A350 has been promoted as a key north–south route linking the M4 corridor to West Wiltshire, Dorset and the south coast. Local congestion in towns such as Westbury, Melksham and Chippenham has been used to argue for road upgrades and bypasses.

The A350 Westbury Bypass was presented as a solution to:

Planners and promoters framed the scheme as a relatively simple local bypass. In reality, it was part of a much larger set of debates about the status of the A350 compared with the A36/A46 and longer‑term ambitions for a strategic north–south route.

4.2 Route options and the Wellhead Valley

A range of route options were discussed over the years. The most controversial proposals involved:

Opponents argued that:

4.3 The White Horse Alliance and local campaigns

In response to the proposals, local residents, parish councils and national organisations came together under the banner of the White Horse Alliance. This coalition became a focal point for opposition to the bypass and a champion for the Wellhead Valley and surrounding countryside.

The White Horse Alliance and other campaigners:

Their work helped to move the debate beyond narrow road engineering arguments towards broader questions of sustainable transport, climate, clean air and countryside protection.

4.4 Public inquiry and decision

The A350 Westbury Bypass led to a significant public inquiry, where the evidence for and against the scheme was tested in detail. The inquiry examined:

Ultimately, the Inspectors and the Secretary of State concluded that the environmental and landscape harm, combined with doubts about the scheme’s benefits and alternatives, meant the bypass should not go ahead in the proposed form.

For supporters of the White Horse Alliance and many local residents, this was a landmark recognition that rural landscapes and community well‑being must be weighed seriously against promises of faster roads.


5. Ongoing Pressures: Road Building & Urban Sprawl

5.1 Beyond one bypass

The cancellation of the A350 Westbury Bypass did not end the story. Instead, it exposed a pattern of recurring proposals and pressures across West Wiltshire and along the A36/A350 corridor.

Themes that continue to reappear include:

Each new proposal tends to reopen the same set of questions about:

5.2 Urban growth around Westbury

Westbury has seen significant growth in recent decades, and further allocations continue to be debated. Key issues include:

Without strong, landscape‑led planning policies, piecemeal decisions can add up to a form of incremental sprawl – hard to reverse and often poorly served by public transport.

5.3 The wider A36/A350 corridor

The A36/A350 corridor links Bath, Salisbury, Warminster, Westbury, Trowbridge and the M4. For decades, national and regional policy makers have vacillated over which routes should carry strategic flows and how best to manage traffic.

Consequences of this uncertainty include:

This blog will explore how decisions at corridor level influence what happens to specific places like the Wellhead Valley, and how a more integrated approach could serve both mobility and environmental goals.


6. Key Themes: Landscape, Clean Air & Rural England

6.1 Landscape protection

At the heart of the Westbury debates is a simple question: what is the countryside for?

Transport and planning decisions need to recognise that landscapes like the Wellhead Valley provide:

The blog will look at how national and local policies on landscape character, green infrastructure and nature recovery can be strengthened and applied along the A36/A350 corridor.

6.2 Clean air and public health

Road traffic is a major source of air pollution and greenhouse gas emissions. Towns along the A36/A350 corridor have faced challenges with:

Protecting clean air is not just an environmental objective; it is a public health priority. This site will explore:

6.3 Rural England at a crossroads

The Wellhead Valley story is part of a much wider question about the future of rural England:

The pressures felt on the edge of Westbury mirror those near many other market towns and villages across England. By following the twists and turns of policy and projects in West Wiltshire, we can learn lessons that apply well beyond one valley or one county.


7. Better Ways Forward: Sustainable Transport & Planning

7.1 Rethinking transport in West Wiltshire

A key theme of this blog is the search for better, low‑impact transport solutions that reduce the need for major new roads while improving everyday mobility.

Potential strands of a more sustainable strategy include:

The question is not whether people should be able to move, but how they move – and how transport choices can support, rather than undermine, the qualities of the Wiltshire countryside.

7.2 Planning for compact, connected communities

Land‑use planning and transport are inseparable. If new homes and jobs are placed in car‑dependent locations, no amount of road building will fix congestion or emissions. This blog will consider:

Good planning can reduce pressure for further A36/A350 road schemes while addressing housing need and supporting local economies.

7.3 Policy, public inquiries and accountability

Public inquiries, local plan examinations and legal challenges play a crucial role in holding decision‑makers to account. Through case studies, documents and commentary, this blog will:

Understanding these processes is essential if communities are to influence the long‑term future of the A36/A350 corridor and rural England more widely.

9. Get involved

The fate of the Wellhead Valley and the Wiltshire countryside around Westbury is not fixed. It will be shaped by the choices made by planners, councillors, ministers, developers and local communities over the coming years.

You can:

This site exists to support that conversation – grounded in the story of the A350 Westbury Bypass and the White Horse Alliance, but looking outward to broader questions of how we plan, move and live in harmony with the landscapes that surround us.


10. Stay in touch

As new content is added, this homepage will signpost recent posts and long‑read features. You are invited to revisit, explore the archives and use the material here to inform local discussions and decision‑making.

The Wellhead Valley may be a small part of Wiltshire, but its story resonates across the whole of rural England: a test of whether we can find transport and planning solutions that respect countryside heritage, community quality of life and the limits of the landscape.
