City transportation in Strasbourg includes the futurist-looking Strasbourg tramway that opened in 1994 and is operated by the regional transit company Compagnie des Transports Strasbourgeois (CTS), consisting of 6 lines with a total length of 55.8 km (34.7 mi). The CTS also operates a comprehensive bus network throughout the city that is integrated with the trams. With more than 500 km (311 mi) of bicycle paths, biking in the city is convenient and the CTS operates a cheap bike-sharing scheme named Vélhop'. The CTS, and its predecessors, also operated a previous generation of tram system between 1878 and 1960, complemented by trolleybus routes between 1939 and 1962.
