Bristol Bridge is a bridge over the floating harbour in Bristol, England. The floating harbour was constructed on the original course of the River Avon, and there has been a bridge on the site since long before the harbour was created by impounding the river in 1809. The current bridge was completed in 1768 and is a Grade II listed building.

Bristol Harbour is the harbour in the city of Bristol, England. The harbour covers an area of 70 acres. It is the former natural tidal river Avon through the city but was made into its current form in 1809 when the tide was prevented from going out permanently. A tidal by-pass was dug for 2 miles through the fields of Bedminster for the river, known as the "River Avon New Cut", "New Cut", or simply "The Cut". It is often called the Floating Harbour as the water level remains constant and it is not affected by the state of the tide on the river in the Avon Gorge, The New Cut or the natural river southeast of Temple Meads to its source.
