A tender is expected to be released shortly following the completion of the studies, with actual construction expected to start in September 2018, according to the company.
The construction of both lines is expected to take four years.
Preparatory works for the two lines are also expected to commence before the end of April.
The two lines will require an investment of MD8.4bn (850m). It is understood that the Moroccan state as well as the regional and municipal governments of Casablanca will supply funding for 60 per cent of the project. Guaranteed loans will be utilised for the remaining 40 per cent of the budget.
The proposed Line 3 will link the Moulay Rachid industrial area, the Ben Msik College, Mabrouka, Ouled Zian and the Hassan II mosque all in Casablanca.
Line 4 will extend from Derb Soltane to the Casa Port.
Line 2 of the Casa Tramway is under construction and is expected to be completed in October 2018.
