On Monday, 11 March 2024, the main work on the third phase of the bridge reconstruction began. The last two phases were scheduled for 2024 and will follow one another seamlessly, thereby shortening the total reconstruction period by one year.

As in previous years, the work involves the complete removal of the bridge deck and all bridge components across the entire supporting structure. In Phase III, the work will focus on the northern half of the northern bridge (closer to Podolí) and the adjacent sidewalk on the bridge abutment. This involves the two right lanes in the direction from the Jižní spojka and the on-ramp from Modřanská Street to Smíchov. The entire parapet with the sidewalk, including the pavement structure, insulation, and leveling concrete, will be completely demolished, and everything will be rebuilt. In Phase IV, work will then shift to the southern section of the northern structure—that is, the two left lanes from the Jižní spojka to Smíchov. Additionally, the bridge expansion joints will be replaced across the entire width of the bridge, and new parapets will be constructed, including railings, guardrails, and guardrail railings. On both sides of the supporting structure, a new pavement system will be laid, including a concrete overlay using special high-strength UHPFRC (Ultra-High-Performance Fiber-Reinforced Concrete) with dispersed reinforcement, which will also serve as insulation for the bridge on this structure. As part of the renovation, the pavement structure will consist of only two layers, instead of the three layers typically proposed. At the end of this phase, both vertical and horizontal traffic markings will be restored, and the on- and off-ramps to and from the bridge will be modified.

Renovation work will also take place inside the bridge, where new prestressing will be installed—one of the most technically challenging tasks. This involves drilling holes in the bridge’s crossbeams, which are located inside the load-bearing structure above the supports. The drill holes will pass through a densely reinforced concrete wall containing prestressing reinforcement and prestressing tendons. This system will provide additional prestressing to the entire structure, ensuring its trouble-free operation for decades to come.
