Colombia’s Toyo Tunnel project in hand

First published05/06/2019

Progress is being made for Colombia’s Toyo Tunnel project. Around 20% of the work has been carried out. Building the tunnel and the first stage of the connecting highway sections in Antioquia includes the construction of 17 bridges, seven tunnel sections and 4.4km of road. Tendering for the second stage of the project is due to start soon and will include building a further 19.4km of highway. The Toyo Tunnel project and the entire highway was originally expected to cost US$603.5 million but is now expected to cost as much as $824.4 million in all, due to unforeseen technical challenges. The route is planned to open to traffic in early 2024.
