Frank Sherwin Bridge, Road bridge near Heuston Station, Dublin, Ireland

The Frank Sherwin Bridge is a three-span reinforced concrete road bridge over the River Liffey, joining St John's Road and the south quays near Heuston Station to Wolfe Tone Quay and Parkgate Street on the Northside. It was designed by Richard Fowler within Dublin Corporation's Road Design Division.

Opened on 28 August 1982, the bridge was built to divert traffic from the older, narrower Sean Heuston Bridge, which had weight restrictions barring trucks and buses. Its opening reversed the quays' one-way system to north quays eastbound and south quays westbound. That year the structure received an award from the Irish Concrete Society.

The bridge is named after Frank Sherwin (1905–1981), a Dublin politician. Its Irish name is Droichead Phroinsias Uí Shearbháin, and the Irish-language name appears alongside English on signage, a detail visitors can spot at the crossing.

Crossing the bridge is part of normal Dublin traffic, so you can access it anytime without worrying about special restrictions or closures. You get the best views of it from both riverbanks, where you also have space to stop and observe the structure.

The structure played a key role in Dublin's traffic planning by removing weight limits from an older nearby river crossing. This meant that heavy trucks and buses could use alternative routes instead of straining the older crossing.
