The Red Cow interchange is a major road junction in west Dublin, Ireland on the M50, meeting the N7 Naas Road (to Cork and Limerick) at a free-flow grade-separated junction which incorporates a tram line. The N7 route commences at this junction, junction 1 on the N7 and junction 9 on the M50, and the Naas Road from the city centre via Inchicore to the Red Cow interchange comprises part of the R110 and the R810. The junction is the busiest road junction in Ireland. In its original configuration, with traffic signals governing many movements, it frequently had tailbacks several kilometres long on the routes leading to it.
