Testing on the Nonthaburi-Kanchanaburi highway in Thailand, also known as M81, will commence in 2024 ahead of its scheduled opening in 2025. Work on the 96.4-km-long motorway is currently 88 per cent completed.

The THB61 billion highway project is part of the Government of Thailand’s public-private partnership (PPP) fast-track scheme. Once operational, the M81 will reduce travel time between Bang Yai and Kanchanaburi from 2.5 hours to just 48 minutes.  

Works on the highway have been divided into 25 contracts, eight of which have been completed. These include the sections between Tha Maka and Tha Muang districts in Kanchanaburi and Nakhon Chaisi and Muang districts in Nakhon Pathom.
