Project Description
Venezia Giulia State Highway SS 14 links the Italian Provinces of Venice, Udine, Gorizia, and Trieste with Slovenia. The bypass crosses 2 km of sparsely populated areas and fields, intersecting the city road Via Gobbi halfway. For greater safety, a 276 m long tunnel was bored under the ground water table using the Pipe Arch method for the solution of the problem. This trenchless tunnel was integrated into two sections of trench tunnel for a total length of 49 m.
