On the night of Saturday 4 March, the central span of the bridge was launched for the People Mover project, which will allow the elevated shuttle bus to cross the by-pass and the A14 motorway.
The bridge that will be called "Link", it’s a fundamental part of the route of almost 5 km that connects the airport with the urban train station. It weighs about 245 tons with 60 meter long span. The central span is the key closing of the A14 bridge along 160 m, consisting of two long lateral shoulders, each 50 meters long. The overall wheelbase of the span, from support to support is 95 m and the radius of altitude curvature is 1000 m. The bridge, dual-runway, prepared for a future doubling of the lane, was built and assembled in the LMV factory in Roverbella (Mantova).
From Friday 3 March, several teams have alternated after an intense preparatory work: 46 operators and 8 technicians were engaged, two 500 ton cranes, a 800 ton vehicle crane, 4 telescopic platforms, 2 telescoping trolleys, a four-wheel steering truck, 2 generators, 4 torque wrenches, 16 hydraulic jacks and 4 power stations.
