SINGAPORE - Travellers catching a flight from Changi Airport's Terminal 1 on Friday morning may want to set off from home earlier, if they are driving to the airport.

The open-air carpark at T1 will close temporarily from 2am on Oct 17 to 2am on Oct 21, as a dry run in preparation for the carpark's permanent closure later this year to make way for the construction of Project Jewel. The $1.47 billion mixed-use complex will be built on the 3.5ha site where the 850-lot carpark is. When completed in 2018, it will have an underground carpark with 2,500 spaces and a link to Terminals 1, 2 and 3, and Changi Airport MRT station.

Here's a video of the relocated facilities by the Changi Airport Group:

During the four-day period when the carpark is closed temporarily, airport staff and traffic marshalls will also be deployed to provide assistance.

Motorists should also take note of the following:

1. Park at Terminal 2 (T2).

2. Motorists can then take the Skytrain to T1. A free shuttle bus service will be added to supplement the existing Skytrain service for transfers between the two terminals.

3. The T1 Arrival pick-up point will be moved from its current position across from the carpark to a new location outside the T1 Arrival Hall.

4. Road signs and lane markings will guide motorists to the relocated facilities, and signs will also be put up inside T1 and T2.

5. To free up more parking spaces, drivers will be discouraged from parking their cars at the airport for extended periods of time. The 24-hour parking fee cap of $20 for cars parked at the airport has been removed with with effect from Oct 14. Drivers now have to pay $57.60 for full-day parking.

6. Motorists who wish to park for an extended period may consider the South Car Park which is near the entrance to the JetQuay terminal. The carpark, which is about a five-minute walk to T2, offers a lower parking rate of 3.5 cents per minute compared to 4 cents per minute at the main terminal car parks. Charges for 24-hour parking are capped at $35 a day.
