National Road 96 – Bari

The aim of the project is the implementation and the safety rehabilition of the Gravina- Bari Road section, in the tract included between the end of the strecht of Altamura road and the beginning of Torritto one.

The road arthery in the concerned area is included in the municipalities of Altamura and Toritto and lays on two important basins. 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 to cross 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).

In reference to the surface hydrography, in the concerned area, that  extends from  the point km 93+598 to the point 99+043, lays only one medium – sized basin whose rainwater is collected by the crossing work n.18 A.P., at the point km 10+350.

The other hydraulic works to cross the road are located at the points km 13+250, km 13+500 and km 13+876.

The remaining part of the road layout, is interested only by the presence of small trenches that collect the water of the road surface.
