A 100-mile network of walking routes across Manchester city centre, including brightly-coloured walkways over canals and rivers, is being proposed.

The CyanLines initiative, expected to cost at least £100m over 10 years, would connect the city’s parks, rivers and canals with major infrastructure projects.

It could also include wooden paths which would appear to float above both the Manchester and Salford sides of the River Irwell, as well as jetties for rowing boats and cycle lanes.

The plans are still at an early concept stage but have been backed by Manchester City Council.
