A section of outbound Vibhavadi Rangsit Road will be closed to traffic on Saturday night, from 10pm to 4am, for the installation of a skywalk at Don Mueang train station on the city's Red Line.
All outbound lanes before Talad Mai Don Muang will be closed during the six hours.
Motorists will be diverted to inbound Vihavadi Rangsit Road, where two lanes will be set aside for them.
After passing the skywalk site motorists will be able to use the road as normal, or they can use Liab Thang Rodfai Kamphaeng Phet 6 Road (a local road), Don Mueang airport’s public relations division said.
Travellers wanting to get to or from the airport are advised to use the Uttrapimuk-Don Muang Tollway to avoid delays.
