The Catalan Transversal Range (Serralada Transversal) is a system of minor mountain ranges at the eastern end of the Pre-Pyrenees, between the Osona and Garrotxa comarques. The existence of the Catalan Transversal Range has made communications in the northern areas of Catalonia difficult in the past, especially between Northeastern Catalonia (Catalan Coastal Depression, with cities like Girona, Figueres and La Jonquera) and Western Catalonia (Catalan Mediterranean System; Lleida, Cervera and further west to Aragón), a problem that has been partly solved with the development of the Eix Transversal.
