I'm not sure how much Chaengwattana area maybe affected since it's afar from the Royal Palace. TAT said "should also be aware that in some areas transportation could be affected. "
- Royal Cremation is scheduled for 25-29 October, 2017. -
- Thursday, 26 October, will be the royal cremation day
TAT provide some other small advices (as usual).
TLDR : Answer Summary
The royal cremation of King Bhumibol Adulyadej in October 2017 is expected to impact transportation in certain areas of Bangkok, though the Chaengwattana area may experience less disruption compared to others. Government offices will be closed during the event, which could lead to atypical traffic patterns, potentially lighter traffic in some districts. However, there might still be congestion from visitors traveling from outside the city.
