Continuing along the route to Llangollen, bridge numbering restarts at 1, while bridges 71 and upwards continue along what is now the Montgomery Canal, but was formerly the Ellesmere Branch to Llanymynech, where it joined the Montgomeryshire Canal. A notable feature of the canal is the Pontcysyllte Aqueduct, built by Thomas Telford. Opened in 1805, the aqueduct is more than long and above the valley floor. It
Llangollen use of canals for leisure took off in the 1970s and 1980s, the route, twisting through Welsh hills and across the Dee Valley on the Pontcysyllte Aqueduct, has made it the most famous and busiest in Britain. The canal is an important part of Llangollen's attraction as a holiday destination. A marina, built at the end of the navigable section, allows summer visitors to moor overnight in Llangollen. The railway was extended from Ruabon, via Acrefair and Trevor, to reach Llangollen by 1865, operating passenger and goods services. The Ruabon to Barmouth Line became part of the Great Western Railway.
