Traffic volume
Traffic lights remained on the expressway until the completion of the last flyover at Fort Road in 1989. The opening of ECP relieved the traffic load of the city area in the 1980s. Traffic volume at Nicoll Highway decreased by 20 per cent, which would otherwise worsen with the new ERP gantries. Robinson Road and Cecil Street were better managed with lesser traffic jams with the declining load all the way to 1990s.
