Detailed Review and Redesign of Upgrading/Widening of Suryabinayak-Dhulikhel Section of Araniko Highway to Six Lane Standard

Project Description

Arniko Highway (H03) is an important link to the hills in the Central and Eastern Regions. It connects the capital city Kathmandu with the Chinese border at Kodari. So far, it is the only motorable link in operation with China. This highway also branches to other feeder roads like Lamosangu-Jiri, Dolalghat- Chautara and others. Arniko highway also connects the urban area of Kathmandu with those in Thimi, Banepa and Dhulikhel. With the eastward growth of the settlement in Kathmandu, the urban traffic on the highway from Kathmandu to Dhulikhel is considerable. The resulting highway and interurban traffic is already beyond the carrying capacity at certain sections during peak hours. With the increasing trade volume between neighboring India and China, the international traffic on Arniko Highway is going to be increased in the coming years. The construction of the dry-ports at the Indian and Chinese borders as well as the forthcoming Kathmandu-Terai Fast Track will in fact facilitate this additional traffic on the highway. Hence it is high time to widen the highway to cater the present traffic, to attract further economic activities along the corridor and to facilitate the resulting future traffic. The widening of the Tinkune (Kathmandu) –Suryavinayak (Bhaktapur) section of the highway has been initiated. This work consists basically of widening of the double lane road carriageway to 4 lanes separated by a median strip and flanked by paved shoulder. On the both side of the highway, service roads will be built under GON funding. Further, Government of Nepal has planned to extend the widening of this highway from Suryabinayak to Dhulikhel. Total length of this section for upgrading works consists of 15.950 km (6 Lanes). Total project cost NRs. 9.60 Billion.

The objective of this consultancy service is to carry out Detailed Review and Redesign of Detailed Design of Upgrading/ Widening of Roads to six lane standard Araniko Lokmarg (Suryabinayaak – Dhulikhel Section), July 2011 for Upgrading/Widening of Road to Six Lane Standard including Revised Detailed Project Report (RDPR).
