The project involving the construction of a highway connecting the industrial municipalities south of the St. Lawrence River, between the towns of Valleyfield and Bécancour, initially saw the light of day in the 1960s. Originally designated “Route 3”, it was officially christened the “autoroute de l’Acier” in 1977. Here are some of the highlights in the production of this long-awaited highway:

• 1968 – A bridge connecting Sorel and Tracy opens to traffic, along with a 6.9 km segment between Highway 116 and Autoroute 20 in Saint-Bruno.
• 1982 – Completion of a 4.8 km segment between Saint-Hubert and Autoroute 10 in order to connect the towns of Tracy and Brossard.
• From 1970 to 1982 – A 9.2 km segment of highway opens, bypassing the town of Salaberry-de-Valleyfield and extending to the municipality of Saint-Timothée.
• 1977 to 1985 – Moratorium on new highway projects in Québec. No segments were added to Autoroute 30.
• 1990 – A single-lane segment opens between Châteauguay and Sainte-Catherine in order to bypass the territory of Kahnawake.
• 1996 – An 11.5 km segment that connects Brossard and Candiac opens to traffic.

Only two sections of Autoroute 30 remain to be completed.

• The Western section, between Châteauguay and Vaudreuil-Dorion
• The Eastern section, south of Candiac, Delson, and Saint-Constant
