Seen here is the Viaduto do Corgo bridge project in the Vila Real region of Portugal. The photo is of over two dozen bridge piers being constructed for a large car and truck bridge. Specifically one can see two slip-form carriages riding up piers and tower cranes built alongside these piers to aid in their construction. Projects like this require many people to work on them, ranging from politicians to get money for the project, to engineers to design the project, to construction works to build the project. In most cases these large scale construction projects employ many thousands of people over the course of years and can stimulate the local economy with the massive influx of works and materials for the bridge.
