During the construction of the Gyöngyös bypass, Colas Út carried out the following work processes:

On the section of Main Road 3 between kilometer markers 79+610 and 80+093, the pavement was reinforced and widened, a weigh station was constructed, and a turbo roundabout was built. By the end of the construction section, a median strip identical in design to the section preceding the roundabout was created between the traffic lanes.

Additional work was also carried out on Main Road 3. Insulation and pavement replacement were performed on the Nagy-patak Bridge located here. The superstructure was repaired, and new curbs were installed. At the same time, a 60-meter-long axle load weighing station was established on both the right and left sides of the main road. The 4-meter-wide axle load weighing station was paved with concrete. In both directions, a 2.5-meter-wide pull-off area was created for inspection vehicles.
