According to the Mass Rapid Transit Authority of Thailand (MRTA), the area from Soi Chaengwattana-Pak Kret 29 to the gate of Sriras elevated expressway will be closed every night until June 30.
Motorists wanting to enter the Sriras expressway must use a flyover and then make a U-turn to enter the expressway.
The MRTA said the Pink Line is 80 per cent complete and some sections should start operating within this year.
