Project Profile on the Dualisation of the Accra – Cape Coast – Road Project (121.7 km)
1.0 Key Issues in the Road Construction Sector in Ghana in 2009.
Over the years, Ghana has been attempting to answer the key challenges to the construction and maintenance of the infrastructure networks that are essential to her economic development and stability. Some of these challenges are:
• Rapid changing society with its associated public infrastructure services needs which are noted to be fast outpacing the resources for providing them;
• Aging infrastructure;
• Cost escalation;
• Limited resources (insufficient budget allocation etc);
• Imbalanced regional development, especially in the Northern Section of the country;
• Safety issues etc.
1.1 The Implementation of the Transport Sector Development Programme (TSDP)
As part of the Transport Sector Development Programme (TSDP) covering the period 2008 – 2013, the Ghana Highway Authority (GHA) has prepared programmes for implementation of the TSDP in order to:
• Reduce vehicle operating costs through maintenance, rehabilitation and reconstruction of roads; and
• Ensure sustainability through development and implementation of cost recovery policies, building and utilizing indigenous capacity in the public and private sectors, and improving financial management and control.
The Accra – Cape Coast dualisation road project is included in the Development Projects component of the TSDP, launched in 2008.
1.2 The Accra – Cape Coast Dualisation Road (121.7 km)
The Accra – Cape Coast road forms an integral part of the National Route 1 (N1) starting from Elubo and ending at Aflao. It is part of the ECOWAS Coastal Trans-West African Highway Network System (Abijan – Lagos corridor), linking Accra to the port of Takoradi, it also serves the administrative and socio-economic needs of the Western, Central, Greater Accra, and Volta regions part.
1.3 Location Part
The route (N1) covers a total distance of about 543.8 km connecting major towns like Agona Junction, Tarkoradi, Cape Coast, Accra, Tema and Aflao.
The 121.1 km project road is a National Route N1 which starts from Kasoa, about 30 km from the Tetteh Quarshie Roundabout in Accra and ends at Cape Coast.
1.4 The route corridor para
The route connects major towns like Kasoa, Winneba, and Mankessim. Majority of the population in the influence area are engaged in the production of staple crops such as maize, cassava, plantain etc. The main economic activities are the production of Winneba (2 No) and at Cape Coast. Along the route can be found three Universities located at many fist class high schools are also located within the corridor. At Mankessim is also found one of the largest markets in Ghana are pineapple and lemon juice, oil palm plantation, and fishing.
1.5 The Project Sections
The route has been packaged into three (3) Sections namely:
• Section 1 : Kasoa – Winneba (31.1 km);
• Section 2 : Winneba – Mankessim (45 km);
• Section 3 : Mankessim – Cape Coast (45.4 km);
The profiles of all the Sections as proposed to be funded by prospective financies to complement the effort of Ghana Government under the TSDP are provided below.
2.0 Outline of the sections within the Accra - Cape Coast Road Project
The existing conditions traffic levels interventions and cost estimates of the respective sections on the route are also discussed below:
2.1 Section 1: Kasoa - Winneba (31.1 km)
The 31.1 km Kasoa – Winneba road is asphaltic concrete surface treated and is in good condition. The carriageway width of the road is 7.3m with 2.5m shoulders on both sides of the road. The weighted Average Annual Daily Traffic (AADT) volume recorded in 2008 on the Kasoa – Winneba section is 9,661 vehicles per day (vpd), comprising 37% of vehicles in the medium group and 4% in the heavy group respectively.
2.2 Section 2 : Winneba – Mankessim (45 km)
The 45km Winneba – Mankessium road is Aspaltic Concrete surface treated and is in good condition. The carriageway width of the road is 7.3 with 2.5m shoulders on both sides of the road. The weighted Average Annual Daily Traffic (AADT) volume recorded in 2008 on the Winneba – Mankessim section is 5,099 vehicles per day (vpd), comprising 38% of vehicles in the medium group and 3% in the heavy group respectively.
2.3 Section 3 : Mankessim – Cape Coast (45.4km)
The 45.4 km Mankessim – Cape Coast road is Asphaltic Concrete surface treated and is in good condition. The weighted Average Annual Daily Traffic (AADT) volume recorded in 2008 on the Winneba – Mankessim section is 6,349 vehicles per day (vpd), comprising 41% of vehicles in the medium group and 3% in the heavy group respectively. The carriageway width of the road is 7.3m with 2.5m shoulders on both sides of the road.
3.0 Source of Construction materials
Along the corridor, five quaries have been established – at Gomoa Fette, Budunburam, Potsin, Ankamu and at Abonko. Gravel materials also abound in the corridor.
4.0 Scope of Projects/Project Components (Sections 1-3)
Under the project, the road will be upgraded to a 2 lane dual carriageway asphaltic concrete surfacing. The route will be designed to comprise the following:
(a) Construction of an additional carriageway including associated drainage structure within all sections.
(b) Construction of 4 No. Interchanges at Kasoa Winneba Roundabout, Mankessim and at Cape Coast.
(c) Provision of 7.3m carriageway width;
(d) Laying of 2.5-metre wide double-surface dressed shoulders on the outer lance and 1.5 metre on the inner lane;
(e) Installation of necessary traffic control devices;
(f) Provision of concrete curbs between side drains and shoulders in towns and villages;
(g) Construction of 2 No. major Rest Stops within the road corridor;
4.1 Project Objectives
The objectives of the Government of Ghana to implement the proposed project include the following:
• To promote a more efficient movement of goods and people between Ghana, Togo, Benin, Nigeria and Cote d’Ivoire along the coastal corridor.
• To foster and facilitate socio-economic development and integration within the West Africa Sub-region.
5.0 Project Justification
The existing road corridor experiences a high level of road accidents resulting in loss of lives and properties as the result of the high amount of traffic on the corridor. Due to the fact that Ghana has struck oil reserves in commercial quantity in the Western Region, traffic volume in the near future on the coastal corridor would grow significantly. This growth in traffic would compound the already poor safety conditions on the corridor. The Dualisation of the Accra - Coast road is to pave way in accommodating the anticipated high traffic volume and improve safety on the corridor and thereby discouraging the occurrence of accidents.
The project when completed will play a very important role in the socio-economic, political and administrative integration of Ghana in general and also strengthen the economic ties between the Western, Central, Greater Accra and Volta Region of the country.
The project is also intended to achieve reduction in vehicle operation cost and travel time of road users. The implementation of the project will also enhance the standard of living of the people in the influence areas and contribute to Government’s effort of bringing development and reducing poverty in the country.
6.0 Status of Implementation
The feasibility studies and preliminary designs are about 60% completed. The Detailed Engineering Design studies of all sections need to be carried out within six (6) calendar months and likely to be completed by April, 2010. Construction of all sections is thus expected to commence by the 1st March of the year 2011.
7.0 Estimated Cost of Project
The Government of Ghana will welcome financial support from Development Partners for the construction of all the Sections. The project is estimated to cost US$300 million. The breakdown is as follows:
• Procurement of Contractors = $0.5 million Construction of Roads and Rest stops = $270 million
• Procurement of Consultants for Construction Supervision = $2 million
• Construction of 4 No. Interchange = $20 million
• Miscellaneous = $7.5 million
TOTAL =$300.0 million
• The implementation of the Accra - Cape Coast Dualisation Road Project would enable the Ghana Government achieve the objective of the project of fostering and facilitating socio-economic development and integration within Ghana and the West Africa Sub-Region.
