Here is the last work selected for the Best Design Award competition, on the occasion of the CTA 2022 which, with our great satisfaction, won the first prize.
A project that we had already taken beyond the borders of Italy in September, when Eng. Costa illustrated in Istanbul, as part of the tenth International Symposium on steel bridges organized by TUCSA and ECCS, the design of the new arch bridge over the Adige river.
Here are some details on the bridge in question:
The road and cycle-pedestrian bridge over the river Adige in Egna is a steel bowstring arch bridge with a single span of 81.4 m. The deck has a multi-cellular box section with an upper deck made of an orthotropic plate. It’s supported by a single inclined arch with trapezoidal section placed in an eccentric position with respect to the cross section; the hangers are made up of I-section profiles with variable height as well as the cantilevers arranged at a spacing of 3.3m to support the cycle and pedestrian path which are external to the cross section of the deck.
The deck will be launched on temporary supports consisting of roller bearings on abutments and a trolley on launching yard. To reduce the cantilevered span, a lattice prop on arrival abutment and a 36m-launching nose are provided; a rear nose will be used for the final launching phases.
The assembly of the work has been completed and the finishing works are nearing completion, the load tests for the static testing of the work will be carried out in December, in anticipation of the opening to the public.
Thanks again to all the CTA organization for the prize awarded to us, we take the opportunity to show you the poster of the winning project, and some photos taken during the days at the CTA (29 September – 1 October 2022 – Francavilla al Mare)
