The 16-station 9.2km Line A will connect Ile Piot in the east with the city's Central Station and Lac Le Pontet in the west of the city, where the line will divide to serve park-and-ride stations at Le Pontet Station and Realpanier.
Line B will link Horloge in the city centre with St Charmand in the southeast of the city, sharing tracks with a short section of Line A east of Central Station. The 5.3km line will have 10 stations.
Construction is set to begin at the end of next year and both lines are due to be commissioned in late 2016.
Alstom will supply a fleet of 24 Citadis Compact low-floor LRVs under a €45m contract awarded by Greater Avignon Metropolitan Council in June this year.
