Eix Transversal
C-25 or Eix Transversal (; lit. Transversal Axis) is a 280 km long primary highway in Catalonia, Spain. 
It crosses the Catalan Transversal Range mountainous region, communicating the northern end of the Catalan Coastal Depression with the Catalan Central Depression.

According to the current coding for highways managed by the Generalitat de Catalunya, the first number C-25 indicates that is mainly a west-eastbound highway, and the second number C-25 indicates that is the fifth southernmost. The road begins at the intersection with Autovía A-2, near Cervera (comarca of Segarra), and finishes at Cassà de la Selva (comarca of Gironès), with a total length of 141 km.

History
The last section of the C-25 to be constructed was finished on December 1997.
The main aims of the construction of this highway were:

 to provide a high-speed alternative way for road traffic between Northeastern Catalonia (Girona, Figueres, La Jonquera...) Catalonia and southern France with Western Catalonia (Lleida, Cervera...) and Aragón, avoiding the often congested Barcelona metropolitan region
 to provide a high-speed connection for Central Catalonia's main towns (Vic, Manresa, Ripoll, etc.), between them as well as with Northeastern and the Western Catalonia
 generally speaking, to create an "orbital route" in what in those days was mainly a radial network with its center in the city of Barcelona, i.e. a road network radiating out from Barcelona.

Despite these aims, the highway was built as a single-lane road and not as a freeway, and soon it was proved to become insufficient for the traffic supported.

On 2007 the Generalitat de Catalunya approved the upgrading of the highway to a freeway, which started on 2008 and is expected to be completed on 2011.
