The Linnhoff TSD1500 MobileMix asphalt plant was used for the project at the busy Tema Motorway Roundabout in southern Ghana. The roundabout had to be improved as it was suffering from heavy congestion at peak periods, with traffic queues often extending up to 1km.
The ‘Project for the Improvement of Ghanaian International Corridors’ was implemented – one of the priority projects proposed in the ‘West Africa Growth Ring Corridor Master Plan’. A US$57million grant from the Japan International Cooperation Agency (JICA) was provided to help with the work. The Motorway Interchange at Tema, Ghana’s largest port city, is the crossroads of two of the country’s busiest international corridors: National Highway 1 (N1), which runs along the Ghanaian coastline virtually all the way between its borders with Ivory Coast and Togo, and, in the far east, National Highway 2 (N2), its main north-south highway which runs to the border with Burkina Faso.
In February 2018, work on the Tema Motorway Interchange began, transforming the roundabout into an interchange with an underpass, the construction of a 2.1km three-lane dual carriageway with 730m underpass on the N1 and improvement of 1.9km of two-lane dual carriageway on the N2. It also included the paving of five service roads and eight ramps for right-turning traffic, a 190m-long box-culvert underpass, four pedestrian bridges, traffic signals and street lighting.
The Linnhoff TSD1500 MobileMix Asphalt Plant produced around 52,000tonnes of hot mix asphalt for the construction of a total of 150,000m2 of asphalt, for use in the base, binder and wearing courses.
The roundabout upgrade is improving the capacity, safety, and efficiency of transport and freight, leading to vastly improved logistics to and from Tema Port, boosting trade.
