Relocation of cable systems for new construction of the B15n finished for now

In preparation for the extension of the B15n between Ergoldsbach and the A92 junction at Essenbach, the network construction department at Josef Rädlinger Ingenieurbau GmbH carried out the relocation of the existing cable systems on behalf of the South Bavarian Highway Authority.

From mid-March, the network construction employees initially uncovered 1,750m of telecommunications cables on the section, relocated 1,100m of these into another route and took away the remaining 650m. In addition, they inserted a 96-fibrous optical fibre cable (OFC) with a total length of approx. 7,200m and implemented the challenging uncovering and relocation of a particularly sensitive 42-paired paper-insulated roadside telecommunications cable. For the relocation, the network construction team carried out controlled horizontal drilling under two public dirt roads and forest paths and established crossings under the A92 and a district road using percussive driving.

Upon completion of this measure, the construction site in this section is free from cables and the extension of the B15n can now begin. Around half of the relocated cable routes are just a temporary measure for now; these consist of elevated cable systems and cable-conduit systems. The network construction department at Rädlinger will move the provisionally relocated cable systems to their final position in a subsequent project before the B15n is due to be completely finished in 2018.
