From Feale's Bridge the route passes the parish of Brosna. Two local roads branch off the R576 to Brosna and Mountcollins, County Limerick respectively. It then enters County Cork passing through the village of Rockchapel. The quality of the road gets very poor from Rockchapel with a series of twisty bends before it passes through the narrow main street in Newmarket where short delays can occur. The route then improves dramatically leaving Newmarket with some stretches of hard shoulder. It then goes through Kanturk with the only roundabout junction on the route before terminating at the N72.
