Jura overpass - A39 expressway
published: 03 05 2000
This bridge is an overpass on the Bourg en Bresse/Dole - A39 Expressway, in France.
This bridge is an overpass on the Bourg en Bresse/Dole - A39 Expressway, in France. The main span, 80 m. long, is a radical fan stay cable design, with a reversed Y pylon with back stays. Two planes of 7 cables - from 15 up to 24 strands - support the suspended deck 60 m. long.
The main span, 80 m. long, is a radical fan stay cable design, with a reversed Y pylon with back stays. Two planes of 7 cables - from 15 up to 24 strands - support the suspended deck 60 m. long.
Three parallel back stays, comprising 61 strands each, anchor the pylon to a concrete foundation plint placed in the ground.
The stays are made of hot-dip galvanised 7 wires 15.7 mm. diameter strands, protected by external black HDPE sheaths, injected with wax. A total of 28 tonnes of strands has been used for the stays. Stay cables are protected at the bottom end by antivandalism steel tubes. The back stays are also fire protected in the lower part.
The concrete deck, cast in situ in three sections, is 13.5m wide and from 0,28 up to 0.40 m. deep. The pylon is 30 m. high from the deck level, included an aesthetic metallic structure on the top.
The stay cables have been installed by a TESACCIAI team performing 2 stressing phases plus final adjustment.
