National Road 11 – Cassano d’Adda

The aim of the project is the realization of a new strecht of road, on the outside of the built-up area of Cassana D’Adda, to reduce and redirect the traffic flow, now condensed on the National Road n.11. In particular, it is necessary to relieve traffic congestion on the urban tract of the Road n.11 that starts with Milano Street, passes throught Vittorio Veneto and Isola Streets and crosses Adda river.

During the first phase of the provided service, HIPRO’s staff has carried out all the detailed studies, necessaries to complete and readjust the preliminary design sections concerning the hydrologic surveys and the hydraulic works, particularly those ones crossing natural trenches and collectors that drain rainwater on the road surface.

HIPRO carried out: deep analysis of the existing situation, with particular reference to the hydrologic and hydraulic matters; analysis relating to the climate and rainfall in the river basin; calculations of the water flow produced by rainfall peaks; design of all the works to retain the existing railway and roads embankments; design and sizing of all the hydraulic works that compose the drainage system of the road ( crossovers works under the road embankment, gutters under road surface, settling tanks to treat the rain that fall in the first munutes of any meteoric occurence). At last, HIPRO has been involved in the verifications concerning the hydraulic compatibility of all the provisional works, necessaries for the realization of the bridge to cross Adda river.
