It then flows through Beaumont and Artane, passing Lorcan Crescent, Coolgariff Road, Kilmore Road and Ardlea Road, where a fully culverted tributary joins from the lands now occupied by Beaumont Hospital. The watercourse then runs by Maryfield Crescent, and on under Mornington Grove, near the Artane Roundabout, to cross the Malahide Road, and then continues through southern Artane and western Harmonstown, coming into Raheny via a siphon under the railway.
