 While the full four-lane divided toll expressways are more favored in recent years due to their higher traffic capacity, a few two-lane expressways do exist, such as the Kempas Highway and the North Klang Straits Bypass.These expressways, however, only have partial access control with at-grade intersections commonly available like most other federal and state roads.Nevertheless, these two-lane highways are still classified as "two-lane expressways" as they are maintained by highway concessionaires, namely PLUS Expressways Berhad (Kempas Highway) and Shapadu (North Klang Straits Bypass).
