First constructed in the 1960s, A-35 is currently a long, 4-lane spur route linking Saint-Jean-sur-Richelieu to Autoroute 10. By 1966, connecting the A-10 in Chambly with Route 104 in Iberville were opened to traffic. Another of A-35 from Route 104 to its terminus with Route 133 were completed in 1967. Completion of the entire length of A-35 had been scheduled for that year in time for Expo 67, but the province instead focused on expediting construction of autoroutes and approach roads to the Expo site. For many years, the A-35 featured at-grade intersections with St-Raphael Road and St-Andre Road in Saint-Luc. These intersections were closed in 1999; the St-Andre Road intersection was converted into a partial cloverleaf interchange, while St-Raphael Road was dead-ended on either side of the A-35.
Future
A federal-provincial funding agreement is providing for the completion of the A-35 to Interstate 89 at the U.S. border. The project's objectives are to improve economic links between Quebec and New England, reduce traffic on Route 133 and improve quality of life in the region. Construction of the A-35 extension began in 2009 between Saint-Alexandre and Saint-Sébastien. Construction of the extension is divided into four segments. The first section of new highway between Saint-Jean-sur-Richelieu and Highway 133 to Saint-Sébastien was opened on October 8, 2014. On June 10, 2019, Federal and provincialgovernment officials announced that plans are in the works to extend Quebec’s Highway 35 by nearly nine kilometres in the southbound direction — but that still leaves it 4.5 kilometres short of reaching the U.S. border. Although Provincial authorities still did not know when the section will be complete, construction of this section was expected to begin in 2020. The Legault government confirmed that Autoroute 35 in the Montérégie region will be completed up to the Canada-US border by 2023. Phase 3 of the work aims to extend Highway 35 from Route 133 in Saint-Sébastien to the junction of Route 133 and chemin Champlain and du Moulin in Saint-Armand. An overpass will be built over Route 202 at Pike River, a bridge will be built over the Rivière-aux-Brochets, an interchange will be erected at the junction of Highway 35, Champlain Road and Route 133 at Saint-Armand and a roundabout will be deployed at the intersection of Route 133 and Champlain and Moulin roads in Saint-Armand. When completed, the length of A-35 will increase to.
