Aside from reducing clearance time for motorcyclists, the diversion has also reduced instances of motorcycle queues ballooning along the Tuas Second Link, ICA said in a media statement.
These motorcycles queues obstruct other road users on the Tuas Second Link, such as lorries and cars, causing massive traffic congestion and cargo delays, it added.
The travel volume at Tuas Second Link is expected to increase further, and the diversion has already received positive feedback from motorcyclists, said Superintendent Lian Zhimin, Senior Assistant Commander of Tuas Checkpoint.
Mr Muhammad Hadi Mohd Hasan, 33, said his wait to clear immigration is now 15 to 20 minutes, down from 40 minutes in the past.
The factory worker drives into Singapore every weekday. Once he nears Tuas Checkpoint, he will try to position his motorcycle on the side of the road that will be diverted to the departure zone.
Mr Tevendran, 22, who washes and polishes cars in Singapore, said his wait is now 10 minutes shorter, giving him some time to eat breakfast.
ICA said it will continue to study Operation Sunrise’s impact over the next six months, and is also exploring the feasibility of a similar diversion at Woodlands Checkpoint, which is undergoing expansion.
