The bridge at Reenmurragha is a different proposition entirely. Carrying a road over a tributary of the Ilen River at the entrance to the New Court demesne, it was built not merely to cross water but to be seen doing so. The downstream elevation rises to about five and a half metres and stretches nearly twenty metres in length, presenting an almost theatrical facade: a semi-circular arch at its base, flanked by pointed blind arches and ogee-headed niches, the latter a Gothic decorative form in which the arch curves outward to a point at the top, like an elongated onion. Pilasters divide the composition into bays, while a parapet wall three metres high carries quatrefoil recesses, each a small circular opening cut into a four-lobed clover shape, and is crowned with paired pointed arches. The effect is of a garden folly pressed into the service of genuine infrastructure.

The ornamental treatment of the downstream face, the side visible from the approach to the demesne, was clearly intended to make an impression on anyone arriving at New Court. Estate bridges of this kind often served as a formal threshold, signalling the transition from public road to private grounds. The upstream side tells a quieter story. There, a low overgrown arch sits alongside an ivy-clad stump of masonry that local tradition identifies as the remains of a watergate, a structure used to control or restrict passage along the watercourse itself. Watergates were common features of managed demesnes, where rivers and streams were treated as boundaries to be regulated as much as the land around them. That this fragment survives, and that its identity has been preserved in local memory, gives the site a layered quality that the polished downstream elevation alone would not suggest.
