Drivers will thus be able to drive on the completely repaired Barrandov Bridge already this year. As in the previous reconstruction phases, three lanes in each direction will be maintained for traffic throughout the reconstruction. The start of this year's phases was preceded by preparatory work carried out by PORR staff throughout the year, which did not restrict traffic on the bridge in any way.
Drawing on the experience of previous phases
The builders have successfully tackled a number of very challenging obstacles during the previous phases over the past two years. The first and second phases of construction work, which included the repair of the entire southern bridge, the reconstruction of the Barrandov ramp and the demolition and rebuilding of the Strakonice ramp, among other things, were a source of very valuable experience. These will now be put to good use by the builders in the implementation of the remaining two phases, which will take place in close succession and should be completed later this year. "The entire implementation team, including the designers, is making every effort to ensure that we can drive on the reconstructed bridge as soon as possible," confirms Martin Ředina, Director of Bridge Construction at PORR.
Progress of the 3rd and 4th stage of the reconstruction
Technically and logistically, the construction will require a high degree of professionalism, as in the previous stages. New external prestressing steel cables will be installed in the bridge chambers, bridge bearings and shutters will be replaced and the original railings will be refurbished. The north bridge, like the south bridge, will be provided with a levelling layer of UHPC - high strength concrete with dispersed reinforcement. This special material was used on such a large scale for the first time in the Czech Republic during the implementation of the previous reconstruction phases, when a greater thickness of asphalt layers was included compared to the tender documentation. The reconstruction of the northern bridge will be completed with a night load test, which will verify the bridge's behaviour under maximum load in different load conditions.
One of the busiest road bridges in the country is undergoing extensive reconstruction as early as 2022, and the main priorities of the general contractor PORR a.s. include handing over the reconstructed bridge in the highest possible quality and in the shortest possible time.
The bridge is being repaired after almost forty years of intensive operation. The reward for the hard work of the bridge builders and the patience of the drivers will be, above all, an extension of its service life and an increase in traffic safety.
