The stretch between the US border and Saint-Jean-sur-Richelieu, where Autoroute 35 begins, is relatively busy, as it provides the main link between Boston and Montreal. Construction to extend Autoroute 35 south of Saint-Jean-sur-Richelieu to the US border by-passing Route 133 started in 2009. Construction was slated to be finished in 2017 but will continue until 2025.[4]
Trucks are prohibited on this road between Saint-Jean-sur-Richelieu and Autoroute 10 (section of 10 km) and between the junction of road 116 in Mont-Saint-Hilaire and Autoroute 20 (section of 3.5 km). Controversy persists and has gained momentum in 2005 between the Ministry of Transports of Quebec and nearly 3000 residents along the road at Saint-Denis-sur-Richelieu, Saint-Charles-sur-Richelieu, and Mont Saint-Hilaire, north of Autoroute 20. The controversy follows the ministry's decision in 1995 to transfer north–south truck traffic from the roads parallel to the 133 and force it to converge, without an impact study, on Chemin des Patriotes, a historical and heritage path that is on a fragile and weak soil and is in the most populated area. The resulting intense heavy traffic generates noise, vibrations, and pollution day and night, which cause health, insomnia, and safety problems in the local population.
