We rebuilt three important intersections in the district Kročehlavy, Kladno into a new form, which brings safer and smoother traffic. At the intersection of the streets Vodárenská, Milady Horákové and Jarosl. Kociána, then at the  intersection of Americká and Vodárenská, as well as between the streets Italská, Americká and the exit from Kaufland – there are now roundabouts. The crossing of four streets solves an unusual connection of two roundabouts, the distance of which would have been too short in the case of an independent arrangement; the remaining two have a regular form.
