Our Construction Intelligence Center (CIC) is currently tracking tunnel related projects with a value of US$1.37 trillion. In terms of the project pipeline value, Europe accounts for the highest share with US$572.6 billion, equivalent to 42% of the total global value of tunnel related projects. Asia-Pacific is in second place, with projects valuing US$477.2 billion. The Americas has projects valued at US$212.3 billion, while the Middle East and Africa has a project pipeline of US$108.9 billion, trailing the other regions.

The global tunnel construction projects pipeline, as tracked by the Construction Intelligence Center (CIC), stands at US$1.37 trillion, and comprises numerous projects related to projects where tunnels are an integral part of the work. Improved transportation links are an important element in the economic development of countries; urbanization in Asia-Pacific and the Middle East and Africa has put a strain on transport infrastructure in these regions, and the more mature regions of Europe and the Americas require the constant upgrading of transport facilities.
