Bangkok’s Samsen Road repair is moving toward a planned 8 October reopening, with crews strengthening the ground, installing drainage and restoring access near Vajira Hospital.
Bangkok officials say the Samsen Road repair is on track to restore traffic by 8 October after damage appeared on 24 September just in front of Vajira Hospital in Dusit. The disruption quickly affected movement in this part of the city, where the road is a key route toward the centre.
What is being done underground
Governor Chadchart Sittipunt inspected the work in person on Saturday and said safety remains the main priority. Crews have already poured more than 1,100 cubic metres of concrete and installed pumps with a capacity of 25 m³ per second to move water away during heavy rain. The ground under the road is becoming more stable as the project advances.
Next steps include spraying concrete to strengthen the soil below the metro station area, filling voids with a sand-and-cement mix, and laying a crushed-stone layer before asphalt is added. Engineers are monitoring each stage and adjusting to new challenges as they appear.
Why the repair matters for the city
Before the road reopens, the city says all underground installations must be completed. That means water pipes, drainage systems and telecommunications cables will be fully laid, reducing the need to dig up the street again later.
At the same time, engineers are reinforcing the foundations of Samsen police station. Officers can still use the building, although vehicles will remain parked there until the work is finished.
Support for residents and wider lessons
Bangkok Metropolitan Administration has opened a coordination centre to provide accommodation and meals for people affected by the disruption, along with updated information on the repair. Workers are also clearing rubble and obstacles, including transformers and power poles. If needed, a 200-ton crane will be used to lift heavy elements safely.
Chadchart thanked MRTA engineers and foreign experts supporting the project, and said the failure has become an important lesson for future work on the Purple Line and Orange Line metro projects. He also praised the prime minister’s visit, saying it helped raise morale.
For residents and visitors alike, the key point is the timeline: Samsen Road is expected to reopen on 8 October. Until then, access around Vajira Hospital and Dusit remains part of Bangkok’s broader infrastructure test, with the city aiming to deliver a safer and more resilient street.
