Is that a light...

at the end of the tunnel?

Dancing this evening - but before that I had a walk round by the canal locks at Marple. This is the little tunnel that passes under the road.

A bit about the Locks.

Marple Locks are situated on the Peak Forest Canal in Marple Cheshire.
The Peak Forest Canal runs from Buxworth in Derbyshire, where an arm also services nearby Whaley Bridge, through Furness Vale, New Mills and Disley to Marple. Here it is joined by the Macclesfield Canal. At Marple the canal descends a flight of sixteen locks, lowering the level by 210 feet before crossing 100 feet above the River Goyt on a magnificent three arched stone aqueduct. The canal continues through Rose Hill cutting, originally a tunnel but opened out many years ago, on to Romiley, Woodley, Hyde, and Dukinfield before its junction with the Ashton Canal. The total length of the canal is a little over fourteen miles.
