The Assam Public Works Department was established in the year 1880 under the British Rule. At the beginning it had the responsibility for all public infrastructure development, construction and maintenance works.
But in the year 1956, the embankment and drainage wing came out of the parent department. The department has undergone considerable expansion after attainment of independence and for smooth functioning of the organization, to share the increasing work load and for providing more stress on developmental works, the Assam P.W.D. was divided into two wings viz Roads and Building wings in August, 1977.
Since then the both the wings are functioning with their prescribed responsibility.
The principal function of the Public works Department is to develop the infrastructure for transport and communication of the state.
Assam PWD discharges its function in construction and repair of roads, bridges, culverts.
