In April 2007 a 2 kilometers demonstration line was opened, built by the Tranvimur joint venture of Acciona and Grupo Cívica, along Avenida Juan Carlos I. The trail was deemed successful in August 2008 and the rest of the system was built after a tendering process, which awarded a contract to Sociedad Concesionaria Tranvía de Murcia, a consortium of the companies Comsa Emte Concesiones and FCC.
