Construction is ongoing for Colombia’s 4868 Toyo tunnel project in Antioquia. The tunnel is located between Giraldo and Canasgordas and some 120km from Medellin. The tunnel should open to traffic in 2024 if the project sticks to its planned schedule. The main tunnel section will measure some 9.85km-long although the project involves drilling side tunnels and emergency areas. The work is costing US$588.4 million.
The highway project for which the Toyo Tunnel forms a key stretch is split into two main stretches. The first section includes 17 bridges, seven tunnels and 4.4km of road, with Antioquia Al Mar holding the concession. The second section measures 19.4km with 11 tunnels and 13 bridges. Colombia’s national Road Institute (Invias) will award the contract for this second section of the route at the start of 2019.
