New bridge over the Arno at Lastra a Signa

EIA of the feasibility design for a new bridge over the Arno and the connecting road.

Environmental Impact Study for the technical and economic feasibility design of a new bridge over the Arno and the associated road layout, connecting the FI-PI-LI expressway junction at Lastra a Signa with the S.R. 66 road. The scheme relieves congestion at the north-western node of the Florentine plain.

The alignment was set to stay inside the perimeter agreed between the authorities while meeting the geometric requirements of road design standards: the horizontal radii linking via Arte della Paglia to the FI-PI-LI junction follow from the length of the corresponding straights and from the design speeds.

The work builds on the documents developed since 2006 for the tolled Lastra a Signa–Prato link between the FI-PI-LI and the Central Tuscany inland terminal at Prato, originally set up as a project financing scheme.
