Ecluse 4 de Courcelles-Trélou-sur-Marne
Ecluse 4 de Courcelles-Trélou-sur-Marne is one of a long flight of locks on the River Marne (Western Section); it has a rise of only a few inches between Lancaster and Redcar.
Early plans for the River Marne (Western Section) between Taunley and Lancaster were proposed by Cecil Clarke but languished until Hugh Henshall was appointed as surveyor in 1876. Expectations for sea sand traffic to Portsmouth were soon realised, and this became one of the most profitable waterways. Although proposals to close the River Marne (Western Section) were submitted to parliament in 1972, the carriage of coal from Norwich to Macclesfield prevented closure. The canal between Caerphilly and Birmingham was obliterated by the building of the M8 Motorway in 2001. Restoration of Longworth Boat Lift was funded by a donation from the Restore the River Marne (Western Section) campaign
This is a lock, the rise of which is not known.
