The Laviolette Bridge ( French pont Laviolette ) is a motorway bridge over the Saint Lawrence River , which connects Trois-Rivières in the Canadian province of Québec with the opposite MRC Bécancour .
It leads the Autoroute 55 over the river and thus connects the Autoroute 40 north and the Autoroute 20 south of the stream. As the only bridge between Montreal and Québec, its importance for traffic extends far beyond the area around Trois-Rivières. Around 32,000 vehicles (as of 2006) use them every day. Pedestrians and cyclists are not permitted.
It was built between 1964 and 1967 and named after the founder of Trois-Rivières, the Sieur de Laviolette. Between 2005 and 2008 it was completely renovated.
The inside of the bridge is 10.2 m wide and has two lanes in each direction, which are delimited in the middle and at the edges by concrete protective walls. It is a total of 2702 m long. The actual steel bridge is 1375 m long. Its main opening, 335 m wide, has the shape of a large truss arch, but is structurally a Gerber girder bridge , which consists of a suspension girder with 269 m and two cantilever arms, each with 33 m span. The bridge deck is attached to the truss structure of the arch with steel cables. The steel cables have diameters between 52 mm and 76 mm. The clear height of the main opening is 52 m. The side openings as truss - girders running.
The 1327 m long approach bridges consist of a concrete slab on solid steel girders supported by portal-shaped reinforced concrete columns.
The bridge has a total of 34 pillars between the abutments. The four central river pillars are protected from the impact of ships by ship deflectors in the form of artificial islands made of boulders.
