The Irwell Sculpture Trail features 30 pieces by local and international artists.

'Walk and look' art took 15 years

It follows the route of the River Irwell from the Lancashire hills down to the Manchester Ship Canal at Salford Quays.

And to mark its completion, a major exhibition will be held jointly at Bury Art Gallery and The Lowry museum.

It is hoped As If I Were A River by Dinu Li will encourage people to walk parts of the trail.

The Irwell Sculpture Trail started in 1987 as the Irwell Valley Way, which was funded by Rossendale Borough Council. The first sculpture that year was Ian Hunter's Willow Tree -- a large environmental maze which spreads over a hillside in a series of tunnels. It can be found outside the Groundwork Countryside Centre in Rawtenstall

In 1997, a £4.2 million Lottery grant was ploughed into regeneration projects -- including flood defences and country parks -- and the Sculpture Trail began.

The final sculpture was Arena by Rita McBride, made from 22 tiers of ferro cement on Littleton Road, Salford.

The exhibition will be at Bury Art Gallery from July 26 to September 20 and at The Lowry from August 2 to October 26.
