Consultancy Services for Road Improvement between Accra and Tema Port Area

Rendel and Ingerop were engaged in 2015 to provide engineering design services for this US$250m (est.) motorway project to improve the road network linking Accra and the Tema Port.

The scope included a 19km motorway section of the National Route 1 (N1), which forms part of the Trans West African Highway (Abidjan - Lagos Corridor) linking Accra and Tema. Development plans included upgrading the existing highway from four to six lanes to enhance travel time and safety of road users. Pedestrian footbridges were a key design feature to prevent crossings at unsafe, unauthorised locations and additional slip roads for the Ashaiman Interchange to facilitate free flow of traffic.
