The new Cosmic Photo Challenge is Technology.
The photo is of a lift bridge in the village of Wrenbury, Cheshire, England.
The lift bridge was designed by Thomas Telford, built in 1790 and is still in use today. It spans the Llangollen branch of the Shropshire Union Canal and carries traffic over the canal. When a boat comes along the bridge is lifted to allow the boat through.
Wrenbury Mill behind the bridge is now used by a company who rent canal narrow boats for holidays. Part of the hire fleet is visible on the right of the photo.
