The Whitby swing bridge.
The swing bridge spanning the Esk divides the upper and lower harbours and joins the east and west sides of the town. Whitby developed as an important bridging point of the River Esk and in 1351 permission was granted for tolls to be taken on the bridge for its maintenance. In 1609 a survey for a new bridge was commissioned while in 1628 it was described as a drawbridge where men raised planks to let vessels pass and tolls were collected. The bridge posts were rebuilt in stone at a cost of £3,000 in 1766. This structure was replaced by a four-arched bridge between 1833 and 1835, one arch made of cast iron swivelled to allow vessels to pass. This bridge was replaced between 1908 and 1909 by the current electric swing bridge.
