Department of Roads (DoR) had been established along with the Department of Building after splitting from the Public Works
Department (PWD) in 2027 B.S. Mr. Dipti Jung Thapa became the Chief Engineer of DoR and served as such from 2027 to
2032 BS. During the Rana regime, there was a road office named "Bato Kaj Goshwara" and"Chhembhadel Adda" for construction
& maintenance of Civil Engineering works. There were branch offices such as "Banaune Adda" for other parts of the country. Then
"Naya Bato Kaj Goshwara" and "Purano Bato Goshwara" were established for new construction and maintenance works
respectively. An army unit called "Samarjung" used to carry out routine maintenance under the"Purano Bato Kaj Goshwara".
Both "Naya Bato Kaj Goshwara" and "Purano Bato Kaj Goshwara" were merged into a new office as the Public Works Department
(PWD), which was located in Singh Durbar after the advent of democracy in 2007 BS. Under PWD two sections were created -
one as a road section and the other as a building section (for all kinds of civil engineering works other than that of roads).
Mr. Kul Ratna Tuladhar was the first Chief Engineer of PWD. "Bagmati Valley Road Project " was set up to carry out the detailed
survey and construction of Kanti Rajpath. In 2011 BS, the Royal Nepal Army completed its detailed survey. In 2017 BS, the Rajdal
Army Battalion completed the construction of 70 Km. of 91 Km. long Kanti Rajpath. In 2017 BS, three sub-sections, named
Construction, Planning, and Maintenance were created under the road section of PWD. Three Chief Engineers were appointed
for each sub-section. They were Mr. Bishnu Bahadur Karki, Mr. Gyan Prasad Sharma, and Mr. Birendra Keshari Pokhrel
respectively. Along with three Chief engineers, the technical adviser Mr. F.J. Chaudeley from UN had been appointed as
engineer-in-chief for technical assistance. In addition, four more technical advisers viz., Mr. Sorber (Design), Mr. Glaister
(Planning), Mr. Zegnate (Maintenance), and Mr. Bell (Mechanical) were appointed from OPEC countries for technical
strengthening of the road department. The Road Transport Organization (RTO) was in existence as a Project Office
separately but it had been winded up in 1962 transferring all its activities to DoR. Mr. B.B. Karki continued as Chief
Engineer till DoR broke away from PWD (2027 BS).
