The project is an extension of existing route between Olbia and Tempio and changes the current road in C1-type road, according to national parameters of the Ministerial Decree 5/11/2001.
The analyzed route is composite by 3 road axis (S.S.127, S.P.136, S.P.38) passing through towns of Tempio, Calangianus, Luras, Sant'Antonio di Gallura, Telti and Olbia.
After analyzing horizontal and vertical profile of existing axis, a first planning idea was discussed with involved local administrations; in the later stage a key planning has been developed and gradually improved during discussions with customer.
The works, conforming to targets requested by Sardinia Region (functionality, technical and economic feasibility), have respected the environmental background, especially typical and fine elements highlighted in the environmental study.
