In addition to a large amount of reinforcement, which did not match the original project documentation, complicated work high voltage cable. The workers discovered it in the supporting structure, it was also not included in any documentation and it was proud. Thus, instead of the planned 16 hours, the motorway was closed in the direction of Prague for approximately 48 hours and in the direction of Hradec Králové for more than 60 hours.
In connection with the cable found in the bridge structure, Pražská energetika (PRE) told ČTK today that the work of the power engineers around the said cable lasted a maximum of an hour. PRE spokesman Petr Holubec further clarified that it was not a high voltage cable, but a historic interconnect cable with a voltage of one kilovolt, which is a low voltage level.
“The cable in these places was before the construction of the highway more than 40 years ago and during its construction, it was unnecessary stored and covered in a bridge structure instead of being under the highway to facilitate work. The builders of the highway and the bridge at that time did not inform anyone about this change, therefore it is not even drawn in historical paper documents, or in digital maps, “said a PRE spokesman, adding that the PRE breakdown service sent a platoon of power engineers to the scene immediately after the announcement of the electric cable shortly after midnight on Sunday. According to Holubec, the power engineers will ensure that they do not have a cable and at 1:25 they handed over the place to the workers for demolition.
