Columbia’s transport minister has said it will take nearly US$168 million and more than two years to finish the controversial La Linea tunnel.

The La Linea tunnel project, or Segundo Centenario tunnel, crosses the central mountain range and forms part of the Bogota-B
In the coming age of the autonomous vehicle, fast and accurate LiDAR surveying will be increasingly important, explains Valdis Vanags. The game-changing introduction of autonomous vehicles relies not only on intelligent traffic systems but well maintained roads to help computer-guided systems navigate using road markings. Laser scanning technology, too, is a game changer when it comes to planning and executing many civil engineering projects, including transport network upgrades and smart city initiatives.
Liebherr’s innovative Free Modeling technology enables road-construction operators to create and modify simple 3D site models directly from their machinery, enhancing real-time decision-making.
The US infrastructure network requires urgent attention - * T Peter Ruane. America's transportation infrastructure was once the "shining light on top of the hill." Major investments in a national highway, bridge, transit, airport, port and waterway system during the 20th century paid great dividends. The free and efficient flow of goods and people across the 50 states led to unparalleled economic expansion. The mobility and prosperity resulting from an interconnected infrastructure was a model for the world
