The new bridges are located on road II/296 between Horn Marov and Pec pod Snkou and are now in a state of permanent maintenance.
The bridges will be fully passable from this week. The debtors gradually removed the temporary bridge. As long as permits allow, they will continue to complete work here, said Dan Lechmann, spokesman for the governor’s office.
I want to thank you for your patience. More than 50 years old bridges were in a state of disrepair and a new one had to be built. The main pillar of the investment was to maintain the availability of transport, as the bridges are only on the only access road to the Giant Mountains. That’s because we were able to rebuild all those bridges in one go to hinder traffic as little as possible in the coming years, says governor Martin Ervek (ODS).
The builders had to meet the conditions of the Krkonoše National Park Foundation, which set the hours in which construction could take place. Another complication was that some of the contracted building materials were not available.
Construction started in May 2021. A shuttle used to run after the temporary bridges in the section between Temný Dol and the switch at Splenho Mlna, there were columns.
The bridges were given a new steel-concrete construction. The steel structures of the beams are made of patinated steel, which does not require surface treatment during its lifetime, so there is no need to make a cut above the roof where there is a protective layer. In addition, no bridges may be cut into the river bed. Self-sufficiency is key to the day-to-day drainage and modernization of aging systems, the Vclave Regional Board of Transportation and Property (ODS) said.
For the construction of the bridge and the rehabilitation of the surrounding roads, the Krlovhradecky region paid 187 million crowns including tax, the most expensive year of road construction. For example, the National Fund for Transport Infrastructure was accommodated. This year, the region is investing 1.2 billion kroner in roads and bridges. The region originally had 872 bridges.
The cars threatened to fall
Last year they discovered a collapse on one of the bridges in Temný Dol, which was built in the 1970s in an 800-meter section. In one city there was even a risk of cars falling onto the road.
Both the concrete and the foundation were affected, vehicles could sink there. All those bridges have the same construction. They are made of concrete girders and between them is a concrete bridge that encloses them. And at first the bridge was very thin, the insulation there was damaged, the bridge stopped, shared the news of the editor of the gossip about the roads of the Krlovhradecky, Ji Koutnk.
Keep an eye out for the detailed condition of the bridge since 2016. The technical condition of the three-bridges at Pece pod Snkou was rated as 3 on the seven-speed switch. After just one winter, the rating dropped to seventh due to arrests and crackdowns, which is why the region decided to demolish them.
Polish bridges, built in the 1970s as part of international cooperation, have low resistance to de-icing agents and poor insulation systems. The mismatch of technological procedures during construction, improper use of materials and weak control of the work could also be blamed, said Ondej Plil, road and bridge inspector of the Krlovhradecky Region Road Department.
