Many roads from the Irish Republic into Northern Ireland were once closed for security reasons, but all are now reinstated, leaving you with a choice of legitimate crossing points. The army checkpoints at approved frontier posts have all been removed, and few customs formalities are observed. The fast N1/A1 road connects Belfast to Dublin in 160 km (100 mi) with an average driving time of just over two hours.
Belfast has many parking garages, as well as street meter-ticket parking. Before parking on the street, check the posted regulations: during rush hours many spots become no-parking.
