New Rangsit-Bang Pa-In highway: traffic jams will soon be a thing of the past!
Something is happening in Bangkok! A new major project is imminent that could make an enormous difference not only for residents, but also for commuters who use the metropolis' streets every day. On December 24, 2024, the Cabinet (KrM) decided that the Road Construction Department (ThL) will start construction work on Highway Number 5, Rangsit-Bang Pa-In section. The whole thing is implemented as a public-private partnership (PPP) in the gross cost model, like Bangkok Biz News reported.
What will the new motorway bring to the region? The main intention behind this is to improve traffic flow on the already busy Phahonyothin and Vibhavadi Rangsit roads. This connection will then link central Bangkok with the northern and northeastern regions of the country, reducing traffic congestion. Project manager Suwichan Suraban has already collected feedback from the private sector and plans to launch the tender in the first quarter of 2026.
Planned construction times and costs
The project will be implemented in several stages. Construction is scheduled to start at the end of 2026 and take around four years, with official commissioning planned for 2023. The total cost is estimated at approximately 42 billion baht, broken down as follows:
- Baukosten: 30.080,8 Millionen Baht
- Betrieb und Wartung: 11.955,6 Millionen Baht
- Start-up-Kosten: 19,4 Millionen Baht
- Kosten für Raststätten: 209,3 Millionen Baht
The new 29-kilometer route will extend the existing Utharapimuk elevated highway and runs along Phahonyothin Road. Seven toll plazas are planned, including Rangsit 1, Rangsit 2 and more. Rest areas with amenities such as toilets and rest areas will also be built.
Connection and infrastructure
Another positive surprise: the project also provides for two connection points to existing roads, which ensure connection to highway number 6 and country road number 32. This will sustainably improve the infrastructure in the region.
This narrative could almost be seen as a metaphor for the challenges faced by people in the growing metropolis of Bangkok. Like Makoto, who survives in his new surroundings and finds his own path, the city must continually assert its place in the changing times.
In any case, both the highway and the fantastic stories from entertainment show how the pursuit of movement and development connects us all. Let's see what the next few months bring in Bangkok!
