The present crossing, with an arch just over a metre and a half wide and less than two metres high, appears to date from the post-medieval period, meaning the bridge recorded in the seventeenth century may have stood somewhere nearby, or may have been replaced entirely, with no way now of knowing for certain.

The earliest written trace of the bridge comes from the Civil Survey of 1654 to 1656, a detailed land census carried out under Cromwellian administration to record ownership and landholding across Ireland. In that document, William Rossiter of Bargy Castle is described as being from Bridge Bargy, and a bridge at the location is listed by name in the survey's index. The Rossiters were a prominent Anglo-Norman family in this part of Wexford, and Bargy Castle itself was their seat. The place-name, anchored to the bridge in the mid-seventeenth century, survived even as the stonework was presumably rebuilt or altered at some later point. What the survey cannot tell us is whether the crossing Rossiter knew was on precisely this spot, or whether the current arch is simply the latest version of a crossing that has shifted slightly over the centuries.
