Estimated at a cost of US$26 million, the project would provide a third-tier interchange on the existing two-tier interchanges, bringing to over 12 the number of interchanges completed or ongoing under the Government.
This phase will involve the construction of a viaduct to link the Tema Harbour Road to the Asiaman Roundabout on the Akosombo Road.
It is expected to be completed within 30 months.
The JFE Engineering Corporation of Japan is the contractor with the CTI Engineering Corporation as the project supervisor.
Other major construction works to be undertaken include a flyover/overpass on the Tema intersection, mechanical stabilisation wall, signal-controlled at-grade intersection and ancillaries works.
Also to be added is 142 metre span continuous composite steel-girder bridge, 2,820- metre steel concrete composite slab, steel box section frame pier, 1.8km bridge and ramps and ancillary road works while the existing traffic lights would be redesigned.
The Japan International Cooperation Agency (JICA) is providing grant funding for the project, which forms part of the Accra-Abidjan transnational corridor highway to improve trade within the West African sub-region and ease traffic flows from Tema to Accra and other surrounding communities.
Vice President Bawumia, cutting the sod on Monday, urged the contractor to ensure adequate traffic management during the construction period to ease traffic flow and minimise the inconvenience to the motoring public.
The government, he said, had constructed a total of 947 kilometres of overlay in the Greater Accra Region since 2017.
The Tema Motorway Interchange Phase 1, Obetsebi Lamptey Interchange Phase 1, Pokuase Interchange (first four-tier interchange) and Tamale Interchange are examples of projects the government had undertaken.
Oher ongoing ones are the Obetsebi Lamptey Phase 2, Takoradi PTC, Nungua, Adjiringanor, Kpone, Savana, Dawhenya, Prampram, and Suame interchanges.
As part of measures to improve traffic flow between Tema and Accra, the Vice President said the Accra- Tema Motorway would be upgraded into a 10-lane facility.
The Phase 1 of the project would be between Tema Roundabout and the Tetteh Quarshie Interchange.
The works would include a four-lane-concrete pavement expressway; three-lane asphaltic concrete service roads on either sides; construction of Lashibi, Community 18 and Teshie Link interchanges and the remodelling of the Tetteh Quarshie Interchange.
He said financing arrangements were being finalised for works to commence soon.
Dr Bawumia said aside those projects, the Government was also undertaking critical road works in the Greater Accra Region, including the Tema-Aflao Road (17km) Phase 1, which involved the provision of service lanes and four interchanges between the Tema Roundabout and Miotso on the Tema-Aflao Road.
Another is the construction of the Tema-Akosombo Road (64km), involving the dualisation of the road and construction of two interchanges at Ashaiman and Asutsuare.
The rest are the dualisation of the Beach Road Phase 1 between Osu and Nungua with the provision of bridges over the Kpeshie and Songor Lagoons ongoing.
The Phase 2 involves dualization of the Beach Road from Nungua to Tema Community Three and includes the construction of a three-tier interchange at Nungua and widening of the railway bridge towards Sakumon, which is at 82 per cent complete.
Ongoing rehabilitation works includes the 23km Dome-Kitase road, involving the provision of access to the Ashesi University, and construction of the Borteyman Road (from School Junction to Nungua Farms), involving the dualisation of the road between School Junction on the Ashalley Botwe Road and the Accra Tema Motorway will provide access to the proposed stadium for the All-African Games.
Also 413.20 km of asphaltic overlay had been laid in Greater Accra from 2021 to date.
This brings the total asphalt overlay works completed in the region to 947.80km.
On behalf of the President, Dr Bawumia thanked the Government and people of Japan who, through JICA, had provided grant funding for the entire works.
He urged the Ministry of Roads and Highways, the consultant as well as the contractor to ensure adequate traffic management measures were in place to reduce the inconvenience the works would cause to the travelling public and residents.
