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 light railway 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. Before a recent upgrade it frequently had tailbacks several kilometres long on the routes leading to it.
Original configuration
Opened in 1990 as part of the M50 Western Parkway project, the junction was originally a grade separated interchange from the point of view of M50 travellers, however for N7 motorists it was a signal-controlled roundabout with negotiation of traffic lights required for all movements. From 1994 onwards the roundabout became the terminus of the N7 road following the decision to detrunk the road inside the M50 (becoming the R110 road).
The nickname Mad Cow roundabout was commonly used to refer to the junction, referring to the slang term given to cattle suffering from the brain disease BSE. The actual name of the roundabout referred to the adjoining Red Cow Moran Hotel.[1]
Upgrade
The junction was upgraded as part of works on the M50 motorway. Congestion was alleviated by providing a third level of grade-separation, allowing Dublin–Cork/Limerick traffic to travel from the M50 to the N7 without having to navigate a roundabout. The junction upgrade was substantially complete by December 2008, with only minor finishing works outstanding. A similar upgrade of the N4/M50 interchange was completed on 20 December 2007. [1].
The junction is now a rather tight spaghetti style interchange, a variant of the partially-unrolled cloverleaf design. There is also a plan to upgrade the junction at Newlands Cross to a grade-separated interchange and preliminary works (to divert a gas main) began in the Autumn of 2008.
Luas depot
The tram depot for the Luas Red Line, a halt (Red Cow) and a Park and Ride are located at the interchange.
The Luas complex added extra traffic to the already-busy junction when it opened in 2004. The tramline crossed the slip roads on the southern side of the junction, as well as crossing half of the road from the city centre before it met the junction (the tram line reaches this point by following the median of the road). The issue of the traffic disruption added by the tram system was seemingly ignored during the original planning of the Luas system. After an outcry over this, government ministers were involved in discussions about the system passing over the junction on "stilts", while the actual construction of the system was underway.
The new interchange keeps trams separated from all other traffic.
