It continues south through Roundwood and the hamlet of Annamoe to Laragh where it meets the Military Road and the Wicklow Gap Road. From Laragh it follows the Avonmore River for 12km (7.5mi) through dense conifer forests and oak woods before terminating in the town of Rathdrum at a junction with the R752.
