Richmond Bridge (also known as Green Bridge) is a road bridge crossing the River Swale in Richmond, North Yorkshire, England. Until the building of Mercury Bridge by the railway station in 1846, it was the only crossing over the River Swale from Richmond. Historically, the bridge carried the Richmond to Lancaster Turnpike, and is now a grade II* listed structure.

History
The bridge was historically known as the Green Bridge as it connected Richmond Green with the south side of the River Swale. The old bridge on this site was narrower, but still had four arches, and also housed a small building in the middle of the bridge for a watchman to maintain an early alarm in case of any danger. The current bridge dates back to 1789, replacing an earlier bridge on the same site, the foundations of which are visible during low water on the west side of the bridge. Flooding in 1771 damaged the old bridge, and this prompted the authorities to have a new bridge built at a cost of £1,800.

Richmond Bridge is made from ashlar stone quarried at Gatherley Moor, and has three moulded arches, each with rounded bays over the piers.

Richmond Bridge is the starting point for the annual Richmond Duck Race, which sees 2,000 sponsored plastic ducks tipped into the river, with the finishing line being Mercury Bridge (Station Bridge) downstream. The Green Bridge is a grade II* listed structure, and a scheduled monument.
