Road and Bridge construction and maintenance activities of RHD are carried out though the 7 (Seven) zonal offices. Each Zone is headed by a Zonal Additional Chief Engineer who is the representative of the Chief Engineer, RHD in his zone.

Under each zone there are two or more Circles which are each headed by a Superintends Engineer. Each Circle is in charge of a number of Divisions each headed by an Executive Engineer and each Division has two more Sub-Divisions each under the charge of a Sub-Divisional Engineer.

Almost all field works are carried out by Private Contractors although some minor maintenance works are carried out by Departmental labor. At the present time the RHD are introducing a number of new contracts systems into the field operations with a view to improving the quality and efficiency of the works. There is also a change in emphasis and funding from construction to maintenance operations.
