New M81 motorway Bangkok (Bang Yai) to Kanchanaburi to fully open by end of 2025
The Department of Highways (DoH) has announced that the M81 motorway, connecting Bang Yai to Kanchanaburi, will be fully operational by the end of this year.
Construction of the 96-kilometre route is almost complete, with finishing touches required for road systems and maintenance work, according to Director-General Apirat Chaiwongnoi.
The motorway passes through four provinces — Nonthaburi, Nakhon Pathom, Ratchaburi, and Kanchanaburi — and features both six-lane and four-lane sections.
It incorporates intelligent traffic management systems, including automatic toll collection via M-Flow, speed detection, and roadside assistance centres.
