OJL Group also works on road infrastructure design. For example, in 2014, OJL Group participated in modernising the intersection of Aleja Krakowska and Mineralna Street in Warsaw. As part of this project, in addition to modernising the roads, a new traffic light system and acceleration lanes, among others, were also implemented.

Obviously, the works must be carried out in such a way that the traffic arrangement plan is disrupted as little as possible; it must also be coordinated with all relevant administrative services, i.e. the Public Roads Administration, underground service providers and so on.
