Expressway is rather a new concept for Vietnamese, traffic is growing rapidly but the major roads are dangerous due to inappropriate design and an inappropriate traffic mix. Expressways would solve these problems along the key corridors, by separating high speed traffic from slower, local traffic.
Vietnam currently recognizes two classes of expressway. Both have a minimum of two lanes in each direction, but Class A has grade separated interchanges, while Class B has at-grade intersections. There are 4 design-speed categories: 60, 80, 100 and 120 Km/h. Generally all cars, buses and trucks are permitted on the expressway but motorcycles of less than 70cm³ engine capacity are not.
Road finance comes from a number of sources including the government, overseas donors such as the ADB, WB, JBIC and business organizations. Road investment recovery is mainly through tolls collected on bridges and roads, in accordance with laws mentioned above.
