Lifford Bridge (in Irish Droichead Leifear) is a cross-border bridge on the A38 connecting with the N15, spanning the River Foyle which marks the border between Strabane in County Tyrone, Northern Ireland, and Lifford in County Donegal in the Republic of Ireland. It remains a vital part of the trans-border route from the North, West and East of County Donegal, to Dublin via County Tyrone.
