This is another sign that is seen in many places in Singapore. They are always building something or repairing something here and then.
We always see "Thank You For Your Co-operation".
One thing about Singapore is that whenever a lane on a road is closed for repairs that will take some time, an alternate lane needs to be provided so that traffic would not be congested. This is something that I noticed.
Do you have signs like these in your city? haha...
