Three main national secondary routes pass through the county. The N52 road passes from Kilbeggan to Tullamore and Birr which then continues to Nenagh where it intersects with the M7. The N62 from Athlone passes through Ferbane and Birr and continues onto Roscrea and Thurles. The N80 route starts in Tullamore and continues to the south east passing through Portlaoise and Carlow. There are no main national primary routes in the county, however, the M6 skirts the county to the north and the M7 skirts the county to the south through Moneygall. Road infrastructure has improved with the completion of the Tullamore bypass in 2009 and improved access to regional cities following completion of the intercity motorway network.
