Traffic going off or on the expressway are controlled through signal lights, and the junctions are listed in numeral order from where it begins after the intersection of Frankfort Avenue and Exeter Avenue to where it ends at the intersection of Northern Expressway and Leavenworth Avenue. However, as Northern Expressway is not direct, the traffic starting from this junction is not very busy at all. Northern Expressway is a dual carriageway, which consists of a green divider. It differs from Grand Boulevard, which is divided by only road markings.
