Con­s­truc­tion work on the res­cue tun­nel for the B39 Schem­mels­berg tun­nel is pro­gres­sing. The base con­cre­ting has been under­way since Octo­ber and 21 base blocks and the tem­po­rary road­way will be com­ple­ted by the end of the year. 

The small cross-sec­tion and limi­ted access opti­ons, which make con­s­truc­tion site logi­stics con­sider­a­bly more dif­fi­cult, pose a chall­enge. In addi­tion to the con­cre­ting work, the sea­lers and iron bin­ders are still working on the con­s­truc­tion site. In Janu­ary, the par­al­lel road tun­nel will be fully clo­sed and the second breakth­rough made. The second phase of the con­s­truc­tion pro­ject beg­ins, in which reno­va­tion, rene­wal of the road­way and tun­nel equip­ment in the exis­ting tun­nel take place in par­al­lel with the struc­tu­ral work in the res­cue tun­nel. The con­sor­tium part­ners PORR Ver­kehrs­tech­nik and Leon­hard Weiss have pro­ven to be relia­ble pro­ject part­ners so far.

The con­s­truc­tion site is on sche­dule thanks to fast and good tun­nell­ing work. By the end of 2025, all trades should have com­ple­ted their work and the tun­nel will be put back into ope­ra­tion with moder­ni­zed equipment.
