In the late 1980s, Cambodia had about 13,350 kilometers of roads, compared with 19,480 kilometers in 1969. Of the current total, only about 20 percent of the roads and highways were covered with asphalt and were in passable condition about 50 percent of the roads were made of crushed stone, gravel, or improved earth and the remaining approximately 30 percent were unimproved earth or were little more than tracks. In 1981 Cambodia opened a newly repaired section of National Route 1, which runs southeast from Phnom Penh to the Vietnamese border. The road, which suffered damage during the war years, was restored most probably by Vietnamese army engineers. In the late 1980s, Cambodia's road network was both underutilized and unable to meet even the modest demands placed upon it by an unindustrialized and agrarian society (see fig. 8.). Commercial vehicles, such as trucks and buses, were insufficient in number and lacked spare parts necessary to keep them running. Road construction and maintenance were ignored by a financially hard-pressed government, while insurgents regularly destroyed bridges and rendered some routes unsafe for travel.
