Air travellers planning to catch flights at Don Mueang from Saturday night to Monday night are advised to leave home early as traffic congestion is expected due to the closure of a main road to the airport.
Pol Col Cherngron Rimpadee, the Immigration Bureau spokesman, on Thursday advised travellers to plan on arriving at least three hours before departure at the airport during the three-day period.
All outbound lanes of Vibhavadhi-Rangsit road near the airport will be closed from 10pm-4am on Saturday, Sunday and Monday to clear space for the construction of the Red Line operated by the State Railway of Thailand.
The closure is necessary for workers to lift a skywalk at Don Muang station.
Two inbound lanes of the road will be temporarily used for the outbound direction at the construction site.
The railway agency and Don Mueang airport recommended travellers to go to the airport by the expressway to avoid congestion.
