S10 dual carriageway, Structure F25

Austria

The S10 is a dual carriageway trunk road under construction in Upper Austria, that forms part of European route 55. For forming the 2-cell cross-section of Structure F25 (the 'Ganglsiedlung' cut-and-cover tunnel), Doka supplied its newly developed Tunnel system DokaCC. The V-shaped strut configuration of this new system makes for easy shoring despite the use of strip footings.
