Tunnel 1 (6,330 metres (3.93 mi)) is a tunnel under construction in the department of Cundinamarca, Colombia. The tunnel is on the road between Tobiagrande and Puerto Salgar. Further on, the road passes through Tunnel 11 (5,370 metres (3.34 mi)). The names were given merely for recognition; in future the tunnels will be named properly, most likely after a notable Colombian. The tunnel La linea is also under construction, and will be the longest tunnel on the country.
