The Department of Highways was established on 1 April 1912. Formerly, there was simply the Department of Canals under the supervision of the Ministry of Agriculture, currently known as the Ministry of Agriculture and Cooperatives. Later, King Vajiravudh (King Rama VI) ordered the Department of Canals to be subordinated to the Ministry of Public Works and renamed the “Department of Roads.” Meanwhile, the Ministry of Public Works was renamed the “Ministry of Transport” according to a declaration regarding the organizational structure of government agencies of 1912.On 30 September 1914, all canal-related divisions of the Department of Roads were handed over to the Department of Irrigation, currently referred to as the Royal Irrigation Department, which was supervised by the Ministry of Agriculture. Therefore, the Department of Roads, led by a director-general, had control over the Road Division.HISTORYHistory20 Annual Report 2025 Department of Highways
On 30 July 1917, after Thailand declared war on Germany and Austria-Hungary, King Rama VI graciously commanded the Department of Roads to merge with the Department of Royal Railways under the supervision of the Ministry of Commerce and Transport, led by the Commander of the Royal Railways. This consolidation aimed to centralize the country’s engineering expertise, as many foreign engineers previously employed by both departments were citizens of hostile nations and had been dismissed or interned. The Department of Roads was led by a chief roadwork technician at the time.On 29 June 1932, with the approval of the People’s Party, King Prajadhipok (King Rama VII) ordered the merger of the Ministry of Commerce and Transport and the Ministry of Agriculture into a single ministry known as the “Ministry of Agriculture and Commerce.” Consequently, the Department of Royal Railways, including the Department of Roads as a subordinate department, was placed under the Ministry of Agriculture and Commerce.On 3 May 1933, with the Cabinet’s guidance and agreement, King Rama VII ratified the Act Establishing Ministries, Sub-ministries, and Departments, B.E. 2476 (1933). The act dissolved the Ministry of Agriculture and Commerce. Hence, the Department of Royal Railways, with the Department of Roads as a subordinate department, was transferred to the Ministry of Economic Affairs (currently referred to as the Ministry of Commerce).On 18 September 1934, with guidance and agreement of the House of Representatives, King Rama VII ratified the Act Transferring Authority and Responsibilities for Highway Construction and Maintenance, B.E. 2477 (1934). As a result, the Department of Roads’ authority and responsibilities were handed over to the Department of Public Works (currently referred to as the Department of Public Works and Town & Country Planning), which was overseen by the Ministry of Interior.On 19 August 1941, during the reign of King Ananda Mahidol (King Rama VIII), the Road Division was promoted to the Department of Roads. Later, it was transferred from the Department of Public Works under the supervision of the Ministry of Interior to the Ministry of Transport pursuant to the Act Restructuring Ministries, Sub-ministries, and Departments, B.E. 2484 (1941). Despite being upgraded to a department under the Ministry of Transport, the Department of Roads had no head office and was still housed in the Department of Public Works’ main office, which was situated at the foot of Phan Fa Lilat Bridge. On 13 November 1948, the department relocated to Rama VI Road, where the Procurement Division is now located.On 12 March 1952, the Department of Roads was renamed the “Department of National Highways” under the supervision of the Ministry of Transport in accordance with the Act Restructuring Ministries, Sub-ministries, and Departments, B.E. 2495 (1952).On 24 June 1955, the Department of National Highways conducted the opening ceremony for its office building on Si Ayutthaya Road.On 4 May 1963, the Department of National Highways was renamed the “Department of Highways” under the supervision of the Ministry of National Development in accordance with the Act Restructuring Ministries, Subministries, and Departments, B.E. 2506 (1963).From 29 September 1972 to the present day, the Department of Highways has been part of the Ministry of Transport in compliance with relevant laws. To conclude, the department’s organizational structure has been improved according to the chronological sequence given hereunder:• The National Executive Council’s Announcement No. 216• The Royal Decree on Organizational Division of theDepartment of Highways, Ministry of Transport, B.E. 2516 (1973)• The Royal Decree on Organizational Division of the Department of Highways, Ministry of Transport, B.E. 2532 (1989)• The Royal Decree on Organizational Division of the Department of Highways, Ministry of Transport, B.E. 2533(1990)• The Act Restructuring Ministries, Sub-ministries, andDepartments, B.E. 2534 (1991)• The Royal Decree on Organizational Division of theDepartment of Highways, Ministry of Transport, B.E. 2537 (1994)• The Royal Decree on Organizational Division of theDepartment of Highways, Ministry of Transport (No. 2),B.E. 2539 (1996)• The Act Restructuring Ministries, Sub-ministries, andDepartments, B.E. 2545 (2002)• The Ministerial Regulations regarding OrganizationalDivision of the Department of Highways, Ministry of Transport, B.E. 2545 (2002)• The Ministerial Regulations regarding Organizational Division of the Department of Highways, Ministry of Transport, B.E. 2552 (2007)• The Ministerial Regulations regarding OrganizationalDivision of the Department of Highways, Ministry of Transport, B.E. 2558 (2015)Annual Report 2025 Department of Highways 21
