West approach viaduct to the bridge across the rowing course

Completed in 2021

The viaduct of 12 spans is formed by a spine box girder with large overhangs supported by precast struts. The deck is erected progressively; at first the spine girder is cast in a formwork suspended on a special overhead gantry with "organic" prestressing system (OPS) that eliminates deflection of the gantry; after that the struts are erected and the deck slab is cast.
