Frank Sherwin Bridge (Irish: Droichead Phroinsias Uí Shearbháin)[2] is a road bridge spanning the River Liffey in Dublin, Ireland.

[4] The bridge was opened in 1982 to remove traffic from the much older and narrower Sean Heuston Bridge as part of an extended traffic management project on Dublin's quays.

Prior to the bridge's opening, the south quays carried all eastbound traffic.

Westbound traffic heading towards St. John's Road West would cross from the north quays via Rory O'Moore Bridge onto Victoria Quay, which had two-way traffic until the Sherwin Bridge opened.

Sean Heuston Bridge had weight restrictions that prohibited truck and bus traffic.
