The Bang Pa-In – Nakhon Ratchasima Intercity Motorway, with route designation M6,
is one of the flagship projects included in the Strategic Action Plan of the Ministry of Transport’s Infrastructure Investment and the Ministry of Finance’s PPP Fast Track scheme,both of which are aimed at expediting the fruition of a range of mega-project plans designed to stimulate the Thai economy.
Civil work of the project, now under construction, is divided into 40 contracts so as to facilitate faster construction tasks thus enabling their meeting the planned work schedules. In regard to the Design and Build of motorway system, operations and system-wide maintenance following official route opening, the Cabinet, via a resolution passed on 22 August 2017, has given an approval for the Department of Highways to invite private entrepreneurs to participate in the investment and running of this project on the Public Private Partnership (PPP) Gross Cost platform, whereby the private sector party is to finance the system installation of motorway facilities for toll collection and traffic control surveillance system as well as to perform system-wide operation and maintenance services (O&M). With the PPP Gross Cost scheme, all toll revenue shall accrue to the public sector party while the private-sector operator shall be remunerated for the costs of system installation and his performance of route operation and maintenance according to pre-defined terms and conditions.

A system with comprehensive access control, the Bang Pa-In – Nakhon Ratchasima Intercity Motorway alignment is approximately 196 km long. The route alignment starts where it connects with the northern segment of the existing Outer Ring Road (or Kanchanaphisek Road) at Bang Pa-In District of Ayutthaya Province, and ends at the approach to the western Nakhon Ratchasima bypass in Muang District, Nakhon Ratchasima Province.
There are ten (10) interchanges linking the M6 with major highways, plus nine (9) toll plazas. Designators and locations of these facilities are listed below:
Interchanges:
Toll Plazas:
In addition, eight (8) motorway rest areas with related facilities for motorway users are provided. These are classified into 3 types as follows:
** Investment in and management of the Motorway Rest Areas are not included in the scope of the PPP for Operation and Maintenance package.
Bang Pa-In – Nakhon Ratchasima Intercity Motorway (M6) Alignment
A new approach will be employed in the construction of the M6 based on the latest motorway standards. Its carriageway will accommodate four to six lanes of traffic, paved with concrete with extra durability and requiring minimal maintenance. Typical Right of Way width is 70m. (ROW extends 20m on both sides where a service road is provided.) Width of a traffic lane is 3.60m; those of inner and outer shoulders, 1.50m and 3.00m respectively. The alignment is comprised of two sections, as follows:
A number of underpasses and overpasses are provided throughout the alignment to minimize any potential impacts that might arise to local residents. Based on terrain conditions, several large viaducts are designed for specific locations, as follows:
4-Lane Motorway
6-Lane Motorway
The M6 will feature a tolled access system wherein tolls will be charged on vehicles according to the distance traveled on the system (i.e. distance-based toll). Manual and Electronic Toll Collection methods will be utilized (i.e. MTC and ETC).
Perspective View of Toll Plaza
Appropriate toll rates have been defined, in compliance with the current economic and social conditions, taking into consideration both the expected toll revenues and the Economic Internal Rate of Return of the Project, as follows:
Type of Vehicle | Toll Rates (Fixed Entry Rate + Distance-Based Rate) |
4-Wheeled Vehicles | Baht 10 + Baht 1.25 /km. |
6-Wheeled Vehicles | Baht 16 + Baht 2.00 /km. |
Vehicles with Over 6 Wheels | Baht 23 + Baht 2.88/km. |
To provide users with motoring convenience, speed and safety, it is essential to have the following systems installed:
Traffic Control Surveillance System
This system will help to reduce road crashes while it promotes more convenience and faster travels. A Control Center Building will be erected that houses a traffic operation center where commands can be relayed to a comprehensive array of traffic control and management system along the route, as described below:
Weight Control System
Two types of vehicle weight control system will be installed at toll plazas, i.e. a Dynamic or Weighing in Motion
System (WIM) and a Static Weighbridge (SWB), in order to prevent damage to the motorway structure due to overladen
trucks. A truck will be directed through the WIM first and be allowed to continue on the motorway unless the weight
carried is exceeding a pre-defined limit. For the latter case, the truck will be required to proceed to the Static
Weighbridge in order for a more accurate weight to be determined.
Hauling Weight Control System
Emergency Rescue System
To offer security and assistance to motorway users in a case of emergency, a number of rescue systems will be
positioned strategically along the project alignment in order for these units to quickly reach the scene of an
incident or emergency.
Rescue personnel and equipment
A development project of this size will quite likely cause some impacts to people as well as its surroundings. DOH therefore made a decision to design the project so as to avoid or minimize any likely impact on nearby communities and the environment. DOH’s care in this area led to an approval for its Environmental Impact Assessment Report (EIA) from the National Environment Board in 2006.
During the years that had transpired, many changes have been brought to the project area. Accordingly, DOH in 2016 decided to commission a re-assessment of the EIA report aiming to review details where significant changes from the previous conditions have occurred. As a result, findings of the new EIA study were approved by the National Environment Board in 2017.
For the M6 motorway construction work to finish and the route opened for service within 2020, DOH has come up with a construction schedule, as follows:
1 Private sector party is to undertake the followings: facilities design, financial sourcing, system construction, toll collection system, traffic control and management system, data communications, power distribution, weight control system, maintenance, emergency rescue, public information service and user assistance.
2 Investment and Operation by a separate private investor: facilities design, construction, financing and operation for the motorway rest areas.
Investment in and management of the Motorway Rest Areas are not included in the scope of the PPP for Operation and Maintenance package.
