The cause of the traffic snarl was likely due free moving highway traffic converged and came to an abrupt halt at the traffic light. At this junction, traffic turning left towards MBFC and Lau Pa Sat entered a two lane road that was subsequently widen by the removal of concrete road dividers into 3 lanes. That did not really help that much and the 2 to 3 km jam was cleared only in mid afternoon.
Many motorists were held up by at least an hour in the jam. By the way, the MCE is underground and underwater, all $4.3b of it. The jam was on a new surface road leading from the exits of the MCE to MBFC.
