The Adriatic Highway (E65) links Dubrovnik to Bosnia and the Croatian city of Split in the north and Montenegro in the south. An extension of the Split-Zagreb motorway is underway, which will, when completed, link Dubrovnik to the Croatian capital, Zagreb. At present only sections have been finished and political problems mean that the final completion date is uncertain (this is currently expected to be sometime in 2010). Driving within the city itself can a nightmare due to the sheer weight of tourist numbers in the high season and a complicated one-way system. Parking spaces are at a premium and the old city is pedestrianised. The phone number for emergency breakdown service is 987. The main bus station is located 2km (1.25 miles) to the north of the old city at Gruž at Put Republike 19 (tel: (060) 305 070). Long-distance operators include Autotrans (tel: (051) 213 821; website: www.autotrans.hr) and Korčula Bus (tel: (020) 711 216) who run services north up the Croatian coast.
