Llangollen Canal not completed until 1805. To join the two halves up, a heavily engineered route from Trevor Basin via Ruabon and Brymbo to the River Dee at Chester was planned, but very little of it was built. Instead, the present route from Frankton to Hurleston Junction on the Chester Canal was constructed, and opened in 1805. To supply the system with water, a navigable feeder was built to Llantisilio, just beyond Llangollen, where the Horseshoe Falls weir was constructed on the River Dee to allow the water to be abstracted. As part of the Shropshire Union system, the canal from Hurleston
Ellesmere Canal eventually incorporated into the Chester Canal, Montgomery Canal and Shropshire Union Canal. Although several major civil engineering feats were accomplished, major building work ceased following the completion of the Pontcysyllte Aqueduct in 1805. The northern end of the navigation's mainline ended from Chester at Trevor Basin near Ruabon and its southern end was at Weston Lullingfields about from Shrewsbury. As part of the rebranding of Britain's industrial waterways as leisure destinations, the surviving central section is now called the Llangollen Canal; even though historically its builders had no intention of sending boat traffic to Llangollen.
