The Land Transport Authority will continue to make further improvements to the newly-opened Marina Coastal Expressway (MCE), said Transport Minister Lui Tuck Yew in a Facebook post on Tuesday night.
In his first comments on the expressway since its opening on Sunday, Mr Lui said the LTA will put up more advisories through multiple channels to guide motorists on the best way to reach their destinations.
Motorists will also be given more information on how far the next exit is and which lanes to take to minimise "last minute weaving action" that slows down traffic, he said.
He noted that traffic flow along the MCE was smoother on Monday evening and Tuesday morning, partly helped by lower traffic volume on Tuesday and motorists becoming more familiar with the MCE.
He said immediate adjustments by the LTA - such as converting a short stretch of Central Boulevard from two to four lanes, improving signages and adjusting traffic light timings - have also helped.
Traffic on Monday morning - the first work day after the MCE opened - was gridlocked in several stretches, particularly around Central Boulevard.
Mr Lui said the LTA will continue to monitor traffic along the MCE and "put in more resources to ensure that traffic will be smooth on 2 Jan when work and school resume".
