Pont de la Poya, Fribourg
The Poya bridge in Fribourg connects Murtenstrasse with Bernstrasse as part of the H182 main road. The 851-metre long structure stretches across the Saane and the sewage plant at an average height of 70 metres above the valley floor. The 10 pillars and 2 pylons that reach a height of 110 metres form 13 bridge sections. The main distance between the pylons is 196 metres. The Palatinat approach viaduct goes directly into the Palatinat tunnel portal.

Construction method:
- Securing the slope on the Palatinat side with bracing prior to the main work
- Flat foundations, foundations on shafts, foundations on bored piles
- Construction of the piles at distances of 4.2 m with large-scale formwork
- Installation of the road plate with concrete design using a formwork carriage
The creation of the metal structure of the road plate is broken down into the following sections:
- Palatinat approach viaduct (252.6 m) in retraction process
- Middle bridge section designed as cable-stayed bridge by cantilever method
- Schönberg approach viaduct (231 m) constructed successively using a heavy lifting crane
