Saltney is a town straddling the counties of Flintshire and Cheshire on the England–Wales border. The local government community of Saltney lies entirely in Wales, while the English areas are unparished. The town forms part of Chester's built-up area and is around 5 miles from Deeside.
Saltney is located next to the River Dee. In the 2001 census the population of the town was 4,769, rising to 5,132 at the time of the 2011 census.
Queensferry (Welsh: Queensferry, sometimes Fferi Buddug or Fferi Isaf) is a town and community in Flintshire, Wales, lying on the River Dee near the border. The community includes the village of Sandycroft. It is between Connah's Quay, Shotton and Saltney Ferry. Queensferry is also part of the wider Deeside conurbation.
The Dee Estuary (Welsh: Aber Dyfrdwy) is a large estuary by means of which the River Dee flows into Liverpool Bay. The estuary starts near Shotton after a five-mile (8 km) 'canalised' section and the river soon swells to be several miles wide forming the boundary between the Wirral Peninsula in north-west England and Flintshire in north-east Wales. The Dee Estuary's largest towns along it include Holywell, Flint, Connah's Quay, Shotton, Queensferry, Saltney Ferry, Heswall, West Kirby and Neston as well as other villages and towns alongside it. The A548 also passes along the estuary in Wales and parts of Cheshire West and Chester and Merseyside in England. The North Wales Coast Line follows the course of the Dee Estuary between Prestatyn and Chester.
