Mercury Bridge (also known as Station Bridge), is a grade II listed structure that crosses the River Swale in North Yorkshire, connecting the town of Richmond to the south side of the river.

[2] Richmond was the terminus of the branch, and besides the station building, it had a vast array of buildings designed by George Townsend Andrews, including the bridge for which he had overall responsibility, but the structural design was carried out by the office of Robert Stephenson.

It was built purely for the public to access the station area, which lay in a different parish to that of Richmond, on the south side of the River Swale.

[8][9] For nearly seventy years, the bridge only led to the railway station, but in the First World War, a contingent of Italian prisoners of war extended the road to Catterick Garrison, and this eventually became the A6136 road.

[13] The bridge has four chamfered pointed arches, each 52 feet (16 m) long, and the parapet is decorated with matching modillions.
