Technical cum Physical Implication under Environmental Study of Proposed Alignment of Outer Ring Road of Kathmandu Valley

Project Description

The concept of Outer Ring Road within the periphery of Kathmandu Valley has been proposed since a decade back following rapid urbanization and increase in population in the old and new settlements outside the present Ring Road. The new project has been conceptualized in such a way that it would ensure infrastructure facilities for 150,000 persons along with necessary measures for environmental conservation and economic opportunities.

The Outer Ring Road scheme has planned to construct an eight-lane road, with a 50 meters wide Right-of-way, while 250 meters of land on both sides of the road will be pooled for its development. The Outer Ring Road is therefore proposed for two components: a) construction of the main road having 50m of Right of Way, b) development of 250m of the land on 250m of the land on either side of the road through the concept of land pooling. The total width in consideration is 550m.

In this context the present study has been carried out to study on the possible alignment of the Outer Ring Road and study its technical and physical implications under environmental aspects of the alignment.

Assignment Description

Perform walkover survey through nodal / control points including projection of intersections due to existing ring road and radial roads (identified 18 major intersections) of the alignment (provided by ORRDP). • Observe the technical implications related to horizontal, vertical and cross-sectional elements, intersections as well as river crossing and cross drainages along the proposed alignment. • Observe physical aspects like land use, built-up area, cultural heritage sites, environmentally sensitive areas, topography (gradient) and main intersections etc. • Use the secondary data, topographic maps, photographs to propose a technically viable alignment
