The flyover on Bangkok's Charan Sanit Wong Road has been closed as of 10pm Monday, January 6, to make way for the Orange Line electric railway development. This closure is a significant step in the construction of the Bang Khun Non-underground station, located at the busy intersection of Charan Sanitwong Road, Liap Thang Rotfai Taling Chan Road, and Sutthawat Road.

With the flyover expected to remain shut for a minimum of two years, the Mass Rapid Transit Authority (MRTA) has announced plans for reconstruction starting in December 2026, with a target completion date in June 2028. Throughout this period, traffic will be limited to just one inbound and one outbound lane on Liap Thang Rotfai Taling Chan Road and Sutthawat Road.

To manage the anticipated traffic congestion, the MRTA has provided alternative routes. Motorists from Ratchapruek Road en route to Siriraj Hospital are advised to navigate via Borommaratchachonnani Road, proceed to Somdet Phra Pin Klao Road, and then onto Arun Amarin Road. An alternative involves using Phran Nok–Phutthamonthon Sai 4 Road, Phran Nok Road, and Wang Lang Road.

For travellers starting from Liap Thang Rotfai Taling Chan Road, the route through Chim Phli Road, Kaeo Ngoen Thong, and Soi Charan Sanitwong 35, leading onto Wang Lang Road, is recommended.

The MRTA has reaffirmed its commitment to prioritising public safety while mitigating environmental and traffic disruptions as this major infrastructure project progresses.
