Plans lodged for €80m upgrade to interchange
The plan involves building a number of new slip roads in the area and removing the signalised roundabout on the northern side of the tunnel to make traffic flow more easily at what is the busiest road junction, outside of Dublin city.
An average of 100,000 vehicles use the junction daily, considerably more than the capacity envisaged when the 335m-long Jack Lynch Tunnel opened in 1999.
