• Bridges in km: 108.654; 117.216; 120.954; 113.449

The contract comprises engineering works, reconstruction of drainage system and removal of trees and shrubs.

The method statement provides for the execution of all building works on the structures in two stages, using the partial closure method of the work execution:

Stage I — building works during all-day closures in track no. 1, with a simultaneous traffic in track no. 2, with the train speed of 120 km/h.

Stage II — building works during all-day closures in track no. 2, with a simultaneous traffic in track no. 1, with the train speed of 120 km/h.
