Among the finest in Asia, Malaysia's road system, which was begun during British colonization, is extensive and covers about 63,445 km. There is a main highway that reaches the Thai border from Singapore, a distance of over 800 km (500 mi). Although Peninsular Malaysia's road system is good, Sabah and Sarawak, have less developed roadways. The majority of interior roads are not that great. Within the city, the Light Rail Transit (LRT) is available for use to help meet Malaysia's need for mobility that is safe, predictable, reliable and comfortable.
