Douglasmouth Bridge is a delightful single arch stone bridge which carries a minor road across the Douglas Water about a mile above its confluence with the Clyde. The bridge carries a single track road, which is notably humped over the arch, between parapets built of ashlar stonework. These show obvious signs of repair, presumably necessitated by cars misjudging the bend on the north bank. The rest of the bridge, including the wing walls, is built of coursed rubble. These wing walls step out over the abutments to provide wider, slightly flared approaches, with a sharp kink at the north west corner to accommodate the bend. The abutments have substantial concrete reinforcement to protect against scouring from the river, but the detailing of the stonework at the springing of the arch, where the abutments step out, is still visible, with small circular piers in the angle. The arch rings themselves are also of ashlar stone, with a cornice moulding around the top.
