Eastern Corridor Road Project, Dodo Pepesu-nkwanta, Ghana

The Eastern Corridor Road, which is designated as N2 on the national road network, runs in a near south-north direction through the Volta Region. It has the strategic importance of being the main arterial south-north road and vice versa in the eastern corridor of the country’s road network. The road together with its contiguous parts now rehabilitated would facilitate easier movement of farm produce and people from the food basket areas of the northern part of the Volta Region, the adjoining Northern Region and the contiguous Upper East Region to the markets of the south.

The Project Involved a Detailed Engineering Design and Construction Supervision of a 46.4km road from Dodo Pepesu to Nkwanta, which is the beginning of Nkwanta – Oti Damanko section of the Eastern Corridor Road Project.

The project also included the survey of Project Affected Persons, Facilitation of Community Engagement and Environmental and Social Impact Assessment Studies

The completed project comprised of two (2) lanes double bituminous seal of 3.65m width x 2, double bituminous shoulder 2.5m width x 2 built with gravel sub-base and crushed rock stone base. Other features include 77no. cross culverts and 4no. Existing bridge rehabilitations, 2.6km climbing lanes as well as provision of walkways and cycle lanes in Nkwanta and Brewaniase. There was also provision and installation of road safety features such as road sign posts, crushed barriers, pedestrian guardrails, road markings and street lighting.
