A programme of rural road improvements will see the upgrade of 100,000km of links in China's Sichuan Province. The work is expected to cost US$2.4 billion. The programme of works forms part of the 12th five-year plan, set out for the 2011-2015 period. The upgrades will result in some 75% of the rural roads featuring asphalt surfaces. In 2011, the plan calls for the upgrade of 20,000km of rural roads in the province.
