The Nantes Busway (line 4) is a bus rapid transit line operating in the city of Nantes, France.
The service was inaugurated on November 6, 2006 and is operated by Semitan.
 The line runs from Place Foch to Porte de Vertou on a dedicated right-of-way, and interconnects with line 1 of the Nantes Tramway at Duchesse Anne Château station.
Four park & ride facilities have been built along the construction of the line to encourage passengers to use public transport.
Nantes Busway line 4 is NF certified (NF stands for French Norm).
A victim of its own success, Busway line 4 attracts higher ridership than Semitan expected, pushing the system to saturation.
Buses are overcrowded at peak times and nearly full off-peak.
Semitan tested the Hess LighTram in November 2009 to eventually increase capacity of the system and relieve overcrowding at peak times.
Though that solution wasn't implemented, Semitan decided to increase passage frequencies to less than 3 minutes at peak times.
If saturation recurs, Busway line 4 may be converted into a Tramway line in the future.
