Then you would have to turn right onto Fr. Mathew Bridge (aka Whitworth Bridge, Dubin Bridge or Old Bridge) and proceed straight onto Church St. if that's allowed, DM.
O'Donovan Rossa Bridge (aka Richmond Bridge or Ormond Bridge) runs between Chancery Place and Winetavern Street, MfH.
P.S. I've had to Google all this too, none of us have a fucking clue.
