Spectacular first images revealed of Castlefield Viaduct extension

Since its opening in 2022, Castlefield Viaduct has captured the imagination of Manchester’s locals and visitors alike, transforming from an industrial relic into a lush urban escape in the heart of the city.

Now, the National Trust has revealed plans for Phase two of this ambitious project, which will see the viaduct expand in both size and scope, creating an even more immersive green space above the city streets.

What to expect in Phase two of Castlefield Viaduct

Currently, the viaduct offers visitors a 150-metre stroll along gardens and green spaces.

But Phase 2 promises to extend this experience significantly, adding an extra 200 metres to the existing walkway. The new designs also introduce a second entry and exit point on the west side of the Mancunian Way, offering a more accessible route into the park via a lift and stairway.

This expansion will feature winding paths surrounded by nature-friendly planting, encouraging visitors to slow down and connect with their surroundings— a moment of calm above the bustling city below.

The vision for Castlefield Viaduct’s future

This next stage is part of a much bigger vision for the Grade II listed structure.

The National Trust, together with its partners, aims to reimagine this iconic viaduct as a place where nature, history, and community converge. Nichola Jacques, Project Manager for Castlefield Viaduct, reflects on the public’s passion for the project:

“We’ve been blown away by the local pride expressed towards the viaduct. Manchester wants this space to reach its full potential— not only as a green haven, but as a vital part of the city’s history and future.”

The Phase 2 transformation will unlock the viaduct’s full deck, allowing for new ideas, opportunities, and investment to take root, making the sky park a permanent fixture in Manchester’s landscape.

Castlefield Viaduct’s story is steeped in history. Originally built over 125 years ago as a Victorian rail route, the viaduct lay unused for decades before being reimagined as a green space. In its second phase, visitors will now be able to explore the untouched section of the viaduct beyond a glass wall—an area that has remained closed off until now.

Matt Cartwright, Founding Director of Twelve Architects, who has been working on the project since 2021, expresses the team’s excitement: “This project is close to our hearts. We’re proud to help unlock the viaduct’s potential, connecting the people of Manchester with nature, heritage, and community.”

Chelsea Flower Show blooms in Manchester

Adding a touch of Chelsea Flower Show elegance to the viaduct, the National Trust has confirmed that WaterAid’s Gold Medal-winning garden from this year’s show will be relocated to Castlefield.

This spectacular garden, designed by architect Je Ahn and landscape designer Tom Massey, is a celebration of water as our most precious resource.

Featuring a rainwater harvesting pavilion, the garden will enhance the viaduct’s green credentials while connecting visitors to the importance of sustainability.

A project for Manchester, by Manchester

Community involvement has been central to the Castlefield Viaduct project from the start, and it remains crucial as the next phase approaches.

The National Trust is calling on the public to share their thoughts on the Phase 2 planning application, which is now live on Manchester City Council’s portal. Public input is encouraged to help shape the future of this space.

Greg Hardie, Associate Director at Arup, highlights the community-driven aspect: “It’s fantastic to see this crucial phase reached. Our collaboration with local architects and community members is integral to realising the vision of creating a vibrant, welcoming space for everyone.”

What happens next?

Construction for Phase 2 could begin as early as 2025, pending planning approval and further funding. The National Trust has already secured £400,000 from National Highways’ Users and Communities Designated Funds programme, but more investment is needed to make this vision a reality.

To help fund the viaduct’s expansion, the National Trust is reaching out to businesses and individuals keen to support the project. Options include joining the Castlefield Viaduct Club or donating through the viaduct’s website.

Castlefield Viaduct remains open to the public throughout 2024, now welcoming visitors from Wednesday to Sunday without the need for advance booking. For those keen to see what’s next for this extraordinary green space in the sky, the future is already beginning to take shape—one winding path at a time.
