The Forth Road Bridge is a suspension bridge in east central Scotland. The bridge opened in 1964 and at the time was the longest suspension bridge in the world outside the United States. The bridge spans the Firth of Forth, connecting Edinburgh, at South Queensferry, to Fife, at North Queensferry. It replaced a centuries-old ferry service to carry vehicular traffic, cyclists and pedestrians across the Forth; railway crossings are made by the nearby Forth Bridge, opened in 1890.

The Scottish Parliament voted to scrap tolls on the bridge from February 2008. The adjacent Queensferry Crossing was opened in August 2017 to carry the M90 motorway across the Firth of Forth, replacing the Forth Road Bridge which had exceeded its design capacity. At its peak, the Forth Road Bridge carried 65,000 vehicles per day.

The Forth Road Bridge was subsequently closed for repairs and refurbishment. It reopened in February 2018, now redesignated as a dedicated Public Transport Corridor, with access to motor vehicles other than buses and taxis restricted; pedestrians and cyclists are still permitted to use the bridge. Starting in or before 2021, Stagecoach Fife will be carrying out the first driverless bus trial to carry passengers in the United Kingdom along a park-and-ride route which includes the Forth Road Bridge as its main section.
