Traffic chaos in Bangkok: Important diversion from November 2025!

Traffic chaos in Bangkok: Important diversion from November 2025!

Things will soon get a little more chaotic in the vibrant metropolis of Bangkok: The Mass Rapid Transit Authority of Thailand (MRTA) has announced an extension of the traffic diversion on Ratchini Street. This measure, necessitated by construction work on the D-Wall (earth wall) of the future Sanam Luang station (OR04) of the Orange Line subway project, affects the stretch under the Phra Pin Klao Bridge to the World War I Volunteers Memorial. The diversion will take effect on November 1, 2025 at 12:01 a.m. and will last until April 30, 2026 at midnight. Although the traffic authority points out that the diversion applies 24 hours a day, only one lane in the direction of Phra Sumera Fort and Thammasat University (Tha Pra Chan) is passable - and that certainly won't provide any relief.

Traffic jams and noise pollution are inevitable. Road users are therefore urged to take alternative routes where possible. Anyone who needs information about the traffic situation can contact 06 3217 6532. There are also regular updates on the Orange Line subway project Facebook page.

Comprehensive diversion for the subway expansion

There has been extensive construction work on the Orange Line subway project since last year, which began on November 15, 2024 at 10:00 p.m. This diversion affected several important stations including Bang Khun Non and Pratunam. While most of the affected routes only require one lane near the sidewalk, the situation at Siriraj station remains stable and there are no disruptions there. Another focus is on the demolition plans for several bridges - depending on the progress of the construction work, these are to be demolished and rebuilt from the beginning of 2025 to March 2026 in order to improve safety standards.

To manage traffic congestion, the Bangkok Metropolitan Administration (BMA) plans to hold a meeting with the MRTA to develop strategies for future traffic management. This includes alternative routes and possibly expanding public transport services, particularly on the busy Phetchaburi Road.

Bangkok: A changing network

The expansion of the subway network in Bangkok is nevertheless a positive sign. The Blue Line, Thailand's first subway, opened back in 2004 and has seen impressive expansion since then. Today, the Blue Line is one of the most efficient connections in the city, with 34 stops and a total distance of around 50 km. The Purple Line, which opened in 2016 and runs largely above ground, and the upcoming Orange Line project will significantly improve the city's transportation infrastructure.

Metro trains are similar to the Skytrain and offer a quick and convenient way to get around the city. Tickets are available from machines or counters, making travel easier for locals and tourists. For environmentally conscious commuters, there are also various discounts for students, children and seniors - a good deal for everyone!

The current changes in transport are a big step in the right direction. While the diversions and construction sites are challenging, the expansion of the subway system will benefit Bangkok in the long term. So anyone preparing for the coming months should keep their eyes open and regularly find out about new developments.
