Achadhantuir Bridge lies on the B869 at the Achmelvich Road End junction, and carries the road over the Uidh a'Chonfhaidh Chuir, which flows out from the Manse Loch into Loch Roe. The Bridge has a concrete deck, faced in stone with stone parapets, carrying a narrow S2 road. It sits on a slight curve, with the parapets extending into flared wing walls on the north bank to accommodate the junction. The design of the bridge is typical of those built across Scotland in the late 1930s and into the 1950s, although it does not appear to carry a datestone, suggesting a later date.
Achmelvich Road End
The road immediately to the north of the bridge forks, with the wing walls flared to accommodate the junction as noted above. The B869, having kinked left to cross the bridge, kinks back to the right, while the minor road leading out to Achmelvich turns to the left along the river bank. On the south side of the bridge, set against the trees facing traffic, there is a sizeable brown tourist sign directing traffic to the popular beaches at Achmelvich and further along the coast.
