The second wave of 4G highway projects includes 10 concessions. 4G involves the construction of 8,000km of roads, including 1,200km of four-lane highways, with the majority of projects to be carried out as PPPs.

In mid November we reported that Colombia's National Council for Economic and Social Policy (CONPES) had prioritized eight new road projects, which included these four that have been tendered.
