Thailand is opening toll-free ways to help ease traffic in the country. The sections of Bang Pa-in-Pak Chong (M6) and Ekkachai-Ban Phaeo (M82) of Thailand’s motorways will open for free travel from August 2022 for a trial period. Thailand aims to open these sections permanently to help improve travel time and accommodate travelers looking for alternate highway routes during peak travel times. These trial sections of toll-free motorways aim to address Thailand’s heavily congested road network.

The initiative is designed to improve transport efficiency, shorten travel times and ease congestion on two important travel corridors — Mittraphap Road, which connects Bangkok with northeastern Thailand, and Rama II Road, a key route towards Samut Sakhon and southern destinations.

Although both motorway sections will initially be available without toll charges, travellers will face different operating conditions. Opening schedules, vehicle restrictions, entry points and road access will vary because some parts of the projects are still being completed or undergoing final system preparations.

M6 Motorway Offers Weekend Travel Alternative Between Bang Pa-in and Pak Chong

The 110-kilometre Bang Pa-in–Pak Chong section of Motorway No. 6 will begin its toll-free trial operation on August 21. However, the route will initially operate only during weekends, opening from Friday afternoon until Sunday midnight.

The weekend-only schedule will continue through the New Year holiday period in 2027, giving travellers an additional option during some of Thailand’s busiest road travel periods.

During the first phase, only four-wheel vehicles will be allowed to use the motorway. A maximum speed limit of 80 kilometers per hour will apply to ensure safe operations while authorities continue monitoring traffic conditions.

Motorists using the M6 route will be able to enter and exit through five interchanges: Bang Pa-in, Hin Kong, Kaeng Khoi, Muak Lek and Pak Chong.

However, travellers heading from Pak Chong towards Bangkok should note that some parts of the Bangkok-bound carriageway are not yet fully completed. Drivers will need to leave the motorway and use Thanarat Road and Mittraphap Road before reconnecting with M6 at the Muak Lek interchange.

The motorway will provide basic roadside facilities during the trial period. Rest areas at Thap Kwang on both sides of the route will be available with toilets and drinking facilities.

However, fuel stations and electric vehicle charging facilities are not yet available along this section. Authorities are advising motorists to prepare before entering the motorway by ensuring they have enough fuel or sufficient battery charge for their journey.

The Pak Chong to Nakhon Ratchasima bypass section of M6 will continue operating free of charge every day, allowing travellers to use the completed motorway section without restrictions.

M82 Opens 24-Hour Route Connecting Bangkok and Samut Sakhon

The second major motorway opening involves the Ekkachai–Ban Phaeo section of Motorway No. 82. The 16.4-kilometre elevated route will begin free trial operations on August 28.

The new section will connect with the existing operational parts of M82, creating a continuous motorway route stretching approximately 25 kilometers along the Bang Khun Thian–Ekkachai–Ban Phaeo corridor.

Unlike M6, which will initially operate only during weekends, the M82 section will be available 24 hours a day.

The motorway will also support a wider range of vehicles. Cars, trucks and buses will all be permitted to use the route, expanding transport options for both private travellers and commercial operators.

Different speed limits will apply depending on vehicle type. Cars will be limited to 80 kilometers per hour, while trucks and buses will have a maximum speed limit of 65 kilometers per hour.

Four interchanges will initially be available for motorists: Phanthai Norasing, Mahachai 1, Mahachai 2 and Ban Phaeo.

The Samut Sakhon 1 and Samut Sakhon 2 interchanges will remain closed during the initial trial stage as further development work continues.

For safety reasons, certain vehicles and users will not be allowed on the elevated motorway. Motorcycles, bicycles, pedestrians, three-wheel vehicles and all types of carts will be prohibited from accessing the route.

New Motorways Expected to Improve Thailand’s Travel Network

The opening of the two motorway sections represents another step in Thailand’s efforts to modernize its transport infrastructure and create more efficient road connections.

The M6 expansion is expected to reduce traffic pressure on Mittraphap Road, one of the country’s busiest routes connecting Bangkok with northeastern provinces. During major holidays and long weekends, this corridor often experiences heavy congestion due to increased domestic travel.

By offering an additional high-speed route, the motorway could improve journey reliability and provide travellers with a more convenient alternative.

The M82 opening is expected to support smoother movement along the Rama II Road corridor, which plays an important role for commuters, freight operators and travellers moving between Bangkok and Samut Sakhon.

The motorway will gradually become a more important part of Thailand’s regional transport network as additional sections are completed and connected.

Travellers Should Check Restrictions Before Starting Their Journey

Although both motorway sections will be free during the trial period, authorities are encouraging motorists to understand the different conditions before travelling.

Drivers should check operating schedules, available interchanges, vehicle eligibility and route limitations before entering either motorway.

The M6 Bang Pa-in–Pak Chong section is designed mainly for weekend passenger travel and currently allows only four-wheel cars. Meanwhile, the M82 Ekkachai–Ban Phaeo section offers a wider transport function with 24-hour access for cars, trucks and buses.

The trial openings will allow transport authorities to evaluate traffic flow, safety performance and operational requirements before the routes move towards full-scale operation.

With Thailand continuing to expand its motorway network, these new routes are expected to provide faster connections, reduce congestion and create more convenient travel choices for millions of road users across the country.
