Rouen
LRT subway

The Rouen Metrobus line was inaugurated in 1994. It is the first L.R.T. project in France developed through a B.O.T. scheme. The L.R.T. line is 16 km long and has 31 stations (of which 5 are underground), it inter-connects the multiple city centers located on both banks of the river Seine. Combined with a thorough restructuring of the bus network, the Metrobus transit system has improved mobility and the quality of life within the metropolitan area.
