The Bargagli-Ferriere Tunnel is a 2,030-metre (6,660 ft) tunnel located on the SP 225 road near Genoa, Italy. It was opened on 15 June 1971 as part of a 4,220-metre (13,850 ft) toll road originally numbered T3.[1] It was the first tunnel to be built with a jet-fan longitudinal ventilation system.[2]
On 22 July 1989 this road, built to complement the SS 225, was renumbered and part of the SS 225 was renumbered SP 77. The designation T3 is no longer used.[citation needed]
