=== Highway network ===
* Total - 38,257&nbsp;km (2004)
** Paved - 2,406&nbsp;km (2004)
** Unpaved - 35,851&nbsp;km (2004)

Of the current total roadway network, only about 50% of the [[road]]s and [[highway]]s are hard surfaced, all-weather, and in good condition. About 50% of the roads were constructed of crushed stone, [[gravel]], or compacted earth. Secondary roads are of 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 a preindustrial [[agrarian society]]. Commercial vehicles, such as trucks and [[bus]]es, were insufficient in number and lacked the [[Auto part|spare parts]] necessary to keep them running. Road construction and maintenance were ignored by a financially hard-pressed governments, while [[Insurgency|insurgent]]s regularly destroyed [[bridge]]s and rendered some routes unsafe for travel.

Cambodia is upgrading the main highways to international standards and most are vastly improved from 2006. Most main roads are now paved. And now road construction is on going from the [[Thailand]] border at [[Poipet]] to [[Siem Reap]] ([[Angkor Wat]]). Funded by over $3 billion of [[China|Chinese]] loans, Chinese companies have built {{Convert|3000|km|mi|abbr=on}} of roads as well as several major bridges.<ref>{{Cite web|title=Over 3,000km of roads funded by China loans, says minister|url=https://elevenmyanmar.com/news/over-3000km-of-roads-funded-by-china-loans-says-minister|access-date=2020-12-11|website=Eleven Media Group Co., Ltd|language=en}}</ref>

An [[Expressways of Cambodia|expressway network]] is being developed, the 190km Phnom Penh-Sikhanoukville expressway (E4) opened in October 2022, the construction to [[Bavet municipality|Bavet]] started in June 2023.<ref>{{Cite web |last=Rogers |first=David |date=2023-04-26 |title=Cambodia plans motorway from Phnom Penh to Vietnam |url=https://www.globalconstructionreview.com/cambodia-plans-motorway-from-phnom-penh-to-vietnam/ |access-date=2023-07-23 |website=Global Construction Review |language=en-GB}}</ref>
