CyanLines is an initiative to create a network of parks, rivers, canals, and walkways across the cities of Manchester and Salford in England. It was launched in September 2025 with four initial routes totalling .
The project's stated aims include linking existing green and blue spacesâÂÂsuch as Castlefield Viaduct, Mayfield Park, and the River IrwellâÂÂwith new routes and infrastructure to support access to nature, active travel, and ecological connectivity.
CyanLines was co-founded by Tom Bloxham, chairman of the property development company Urban Splash, and Pete Swift, chief executive of the architecture practice Planit. The name refers to the project's focus on integrating blue (water) and green (natural) spaces. The initiative was launched on 10 September 2025 at Aviva Studios in Manchester, with involvement from Manchester City Council and the Greater Manchester Combined Authority.
The aim is to repurpose underused urban areas to create routes incorporating biodiversity and public space. Proposed connections include established sites such as Castlefield Viaduct, Mayfield Park, and New Islington Marina, along with smaller parks and planned developments including Victoria North and Holt Town.
Public-sector involved in the CyanLines initiative include Manchester City Council, Salford City Council, and the Greater Manchester Combined Authority. These organisations contribute to the project's strategic direction and its alignment with regional planning and policy frameworks.
Private-sector participants include developers and design firms such as Urban Splash, Planit, Allied London, Bruntwood, Far East Consortium, Landsec, Property Alliance Group, and Renaker. Their roles relate to development activity and design work associated with areas included in the proposed network.
In the charitable sector, the National Trust and Factory International are listed as supporters of the initiative. Their involvement relates to cultural, environmental, and communityâÂÂfocused aspects of the project.
CyanLines receives funding from a combination of public and philanthropic bodies. Confirmed contributors include Natural England and the National Lottery Heritage Fund's Nature Towns and Cities programme, which support projects related to green and blue infrastructure and communityâÂÂbased environmental activity.
As of September 2025, CyanLines is in the process of establishing a dedicated not-for-profit organisation, potentially a community interest company or charity, to manage governance, broaden partnerships, and secure long-term funding for the initiative.
The first four CyanLines routes, launched in Manchester city centre and stretching a total of , include:
