The Stroudwater canal in Gloucestershire was built in the 1770s. It brought coal to the mills along the Stroud valleys, which had become an important centre for the manufacture of woollen cloth, but the arrival of the railways in the mid 19th century led to the canal's decline and eventual abandonment. A mile-long section of it was filled in when the M5 motorway was built in the 1960s, cutting the canal off from the rest of the inland waterways network. Now ambitious multi-million plans are underway to restore and re-open the "missing mile" and reconnect the canal.

Martha Kearney visits the Stroudwater canal to see how the work is going. She talks to volunteers, and finds out what difference the work will make to the canal - as a local amenity, as a tourist attraction and as a wildlife corridor.
