Between its junction with the M7 and Dunkettle, the M8 passes through pasture in County Laois, and over bogland and coniferous forest through County Kilkenny and County Tipperary. South of Cashel, it enters the Golden Vale and crosses the River Suir west of Cahir. The motorway then travels south-west along the Galtee Mountains, passing Glengarra Wood and Mitchelstown Cave. East of the route, the Knockmealdown Mountains and the Comeraghs are starkly visible. The M8 crosses into County Cork south of Kilbeheny and proceeds south to the east of Mitchelstown, before skirting around the base of Kilworth Mountain through pastoral farmland and demesne parkland. At Moorepark, some 5 km north of Fermoy, the M8 is tolled for the next 17.5 kilometres. This tolled section incorporates an impressive 450m viaduct crossing of the River Blackwater. Toll plazas are located between junctions 16 and 17 and at the southbound exit of junction 15. The current toll for cars is €1.90. Many motorists, particularly lorry drivers, drive through Fermoy, Rathcormac and Watergrasshill to avoid the toll. In 2006 the Irish Road Haulage Association advised its members not to use the toll road, because they considered it to be too expensive. Consequently, traffic volumes through Watergrasshill increased by about 6,000 vehicles (of which approximately 1,100 were lorries) per day at the end of that year. By the end of 2008 increasing numbers of vehicles were opting to pay the toll. The M8 continues south, bypassing Watergrasshill, Sallybrook, Riverstown and Glanmire, before ending 450m north of the Jack Lynch Tunnel at the approach to the Dunkettle Interchange, which connects it with the N25 to Waterford, the N40 Cork South Ring Road and the N8 to Cork city centre. Despite having a nominal nineteen junctions, the motorway in fact only has eighteen, because the proposed junction 2 was never constructed.
