New expressway linking Bangkok’s west with inner capital ready to open ahead of schedule


Residents living in the western part of the capital will soon travel to the inner zones of the capital faster as now the new expressway, Si Rat-Outer Ringroad, is 99.2% finished and is expected to open ahead of schedule in August.

This 16.7 kilometres long expressway will allow them to travel into central Bangkok much more convenient.


The Si Rat Expressway Project – Outer Ring Road is part of a plan to extend Bangkok’s Metropolitan Expressway network to the western portions of the capital.

The expressway starts from Kanchana Phisek road, close to the Mahasawas Water Filtration Station.

The expressway initially runs along the State Railway of Thailand’s southern rail tracks before crossing the Chao Phraya River close to the Rama 6 Bridge.

It terminates in Bang Sue district just north of the Mo Chit 2 Bus Terminal descending to the Kamphaeng Petch 2 Road.

As of this report, approximately 99.2 % of the work has been completed and the expressway will officially open ahead of schedule in August.

Previously, it was scheduled to be opened during the latter part of the year but the earlier than expected opening will greatly help to reduce the heavy traffic congestion in western Bangkok.

With regards to tolls, 4-wheeled vehicles will be charged 50 baht per vehicle while 6 to 10 wheelers are charged 80 baht. For larger vehicles with more than 10 wheels, the toll charged will be 115 baht per vehicle.
