The Project

The project is divided into two lots, and includes the construction of a 4-lanes arterial road, as by pass of the existing Motorway n. 9 (“Via Emilia”). Featuring a 7.5 km total length, the bypass connects the Motorway n.9 to another ringroad section, namely the “East Ringroad”, allowing to over-ride the northern town sector and thus relieving the urban traffic currently resting on the inner roads.

The works of the first section (about 5.5 km) concern the doubling to four lanes and the modernization of an existing arterial road connecting Motorway n. 9 to the State Road n. 67 “Tuscany-Romagna”.

The works of the second portion consist instead in the construction of a new 4-lanes infrastructure that will ensure the connection to the ringroad. The main headwork of this section is a 1 km long artificial tunnel that allows the under crossing of the streets of “Via Ravegnana”, “Via Macero Sauli” and “Via Bertini”. Such Tunnel connects the municipal roads through two roundabout junctions. Many security systems have been adopted for this tunnel: video surveillance systems, variable-message signaling panels, Sprinkler Systems. Despite regulatory standards do not impose “escape routes” to the surface, such facilities have been designed and distributed at regular distances of 300 meters.

The headworks concerning the Bypass are also an important feature of the new Forlì ringroad system and will make it possible to simplify the northern city traffic by doubling and upgrading the “Villanova – via Ravegnana” section and to create the tunnel that leads to the East Ringroad. Such infrastructure also constitutes a strategic asset for the development of the productive and economic sector by directly connecting the main industrial districts and the transportation nodes.
