The road network in Jamaica consists of almost 21,000 kilometres of roads, of which over 15,000 kilometres is paved. The numbering scheme used covers freeways, primary (or A) roads, secondary (or B) roads, parochial roads and unclassified roads.
Starting in the late 1990s the Jamaican Government (in cooperation with private investors) embarked on the Highway 2000 project to create a system of motorways, the first such access-controlled roads of their kind on the island. The project seeks ultimately to link the two main cities (Kingston and Montego Bay) and the north coast. It is being undertaken as a series of phases:
Phase 1a was the 33 kilometre Kingston-Bushy Park Highway (in actuality, from the Manley Highway at Caymanas Park to Sandy Bay) which was completed in 2003, and the upgrade of the Portmore Causeway, completed June 2006.
Phase 1B Sandy Bay to Four Paths which was completed in August 15, 2012 and opened as the T1 Toll Road. There is an exit for traffic to/from the A1 Spanish Town Bypass between 9.7km and 11.2km from the eastern end of the T1, then to Old Harbour at 26.5km, to Freetown at 30.9km, to Sandy Bay at 42.3km, and concludes at a junction with the A2 at 45km, about 400m east of the junction with Glenmuir Rd providing access to May Pen. Work on the section from Four Paths to Williamsfield has yet to start. This phase will be a total of 37.7 kilometres when completed.
Phase 2a Caymanas Park-Ocho Rios. The section from Linstead By-Pass to Moneague opened as the T3 on 5th August 2014, 19.1 km. The link to the A1 Moneague to Mount Diablo Road at 16.5km from Linstead remains closed at this time. This exit allows northbound traffic to exit to the A1 and southbound traffic to join the T3.
Phase 2b Mandeville-Montego Bay.
On 2009-09-15 Jamaica's prime minister, Bruce Golding, announced to Parliament that Highway 2000 was to be renamed in honour of Usain Bolt. Those intentions were sidelined following a news paper article claiming Bolt had rejected the proposal.
