Construction of passing lanes on main road 21
Starting out in the centre of Hatvan and crossing the M3 motorway, main road 21 runs north towards Salgótarján in the valley of the Zagyva River. As traffic kept growing heavier, the risk of accidents also increased. To provide a solution, two passing sections were constructed 5 km apart in a length of approximately 2 km, respectively. In line with the corresponding contract, the existing 2×1 lane legs were widened to 2×2 lanes.
