Maybe sooner, if electric motive power becomes standard intercity. Cross beams probably would not give adequate clearance for overhead supply. New structure would seem most economic and less disruptive of service, existing being retained for future upgrading or third line.
Existing rail allignment and station location indicates position quite near existing viaduct. East would interfer least with view of existing from Drogheda side. Cable stayed bridge would least block view from west. Contrast old/new would make aesthetic statement.

Boyne bridge on M1 cost €35m, 350m long overall, 170m main span , six traffic lanes wide.
Maybe Transport 21+?
