Quebec Route 112 is a provincial highway in Quebec that runs east–west between Quebec City and Rivière-du-Loup, traversing urban and rural regions of Chaudière-Appalaches and Montérégie. The corridor links major municipalities such as Lévis, Saint-Hyacinthe, Victoriaville, and Drummondville, serving as an alternative to Autoroute 20 and connecting to arterial routes including Autoroute 73, Autoroute 55, and Autoroute 10. The route passes near landmarks like Parc national de la Jacques-Cartier, Basilica of Sainte-Anne-de-Beaupré, and the industrial zones of Sorel-Tracy.

Route description

Route 112 begins at a junction near Downtown Quebec City and proceeds into Lévis along corridors adjacent to the Saint Lawrence River, intersecting local arterials and feeding commuter flows to Palais municipal de Québec, Laval University, Plains of Abraham, and Citadelle of Quebec. Continuing southwest, the highway crosses agricultural plains toward Sainte-Marie-de-Beauce and the Beauce region, passing near cultural centers such as Musée de la civilisation and Théâtre du Vieux-Terrebonne, before entering the Centre-du-Québec region and urban nodes like Victoriaville and Drummondville. Eastward segments run parallel to Autoroute 20 between Saint-Hyacinthe and Sorel-Tracy, with access to industrial parks including Zona-Center Saint-Hyacinthe and logistics hubs serving companies such as Bombardier and CAO Group. Approaching Rivière-du-Loup, the highway connects to ferry services and provincial facilities near Parc des Chutes and regional hospitals like Hôpital régional de Rimouski. The corridor traverses mixed landscapes including the St. Lawrence Lowlands, river valleys near Rivière Chaudière, and foothills of the Notre Dame Mountains, linking to heritage sites such as Maison nationale des Patriotes and community centers like Centre culturel de Drummondville.

History

The alignment traces historic trade and postal routes used during the New France era and early Confederation road-building initiatives overseen by provincial ministries. Early 20th-century improvements were influenced by the rise of automobile travel and industrial growth tied to companies like Eaton's and Alcan, prompting upgrades near manufacturing centers such as Drummondville and Saint-Hyacinthe. Mid-century expansions paralleled the construction of the Trans-Canada Highway network and the development of Autoroute systems; this produced bypasses around municipal cores associated with projects funded by provincial authorities and influenced by planners linked to institutions like Université de Montréal and McGill University civil engineering departments. Late 20th- and early 21st-century initiatives addressed safety and capacity, including reconstruction near Victoriaville and interchange work connecting to Autoroute 55 and Autoroute 20; stakeholders included regional county municipalities such as MRC de Drummond and economic development agencies like Investissement Québec.

Major intersections

The route connects with multiple major corridors and urban thoroughfares: - Junction with Autoroute 73 near Lévis providing access to Quebec City and Saint-Georges. - Interchange with Autoroute 20 at points serving Saint-Hyacinthe and Sorel-Tracy. - Crossings with Autoroute 55 adjacent to Victoriaville linking to Sherbrooke and Trois-Rivières. - Connections to Autoroute 10 via regional roads toward Montreal and Bromont. - Access to secondary routes feeding Drummondville industrial zones and to local municipal streets in L'Islet and Kamouraska. These intersections enable freight movements to ports such as Port of Montreal and Port of Quebec and support commuter links to institutions like Cégep de Drummondville and Université Laval.

Traffic and safety

Traffic volumes vary from urban peak flows near Quebec City and Saint-Hyacinthe to lower rural counts in sectors of Chaudière-Appalaches, with seasonal increases due to tourism toward sites like Basilica of Sainte-Anne-de-Beaupré and agricultural shipments from Beauce farms. Safety concerns have prompted measures such as speed limit adjustments, median barriers, and intersection redesigns influenced by traffic research from INRS and regional police forces including the Sûreté du Québec. Collision hotspots have been identified near commercial corridors in Drummondville, and local governments have implemented lighting, signage, and pedestrian crossings coordinated with emergency services like Urgel Bourgie and hospital networks. Freight regulations and vehicle inspections are enforced by provincial agencies and carrier groups such as Canadian Trucking Alliance.

Public transportation and services

Route 112 supports regional transit services including intercity bus operators like Orléans Express and community shuttle programs coordinated with municipal transit authorities in Lévis, Drummondville, and Victoriaville. Park-and-ride facilities and commuter lanes interface with commuter rail projects and bus rapid transit proposals linked to planners at AMT and municipal planners from Ville de Montréal for integrated mobility. Roadside services include rest areas, service stations branded by companies such as Petro-Canada and Esso, as well as emergency call boxes and maintenance operations managed by provincial road crews and contractors, some affiliated with construction firms like SNC-Lavalin.

Future developments and upgrades

Planned projects consider capacity upgrades, interchange reconstructions, and safety retrofits funded through provincial capital programs and federal-provincial partnerships observed in transportation plans from Ministère des Transports du Québec. Proposals include corridor twinning near high-traffic sections, roundabout installations at rural intersections, and intelligent transportation systems deployments modeled on pilot programs in Montreal and Quebec City. Stakeholder consultations involve municipal councils, regional economic development agencies such as Chambre de commerce du Montréal métropolitain, environmental assessments referencing Ministère de l'Environnement et de la Lutte contre les changements climatiques, and consultations with indigenous communities represented by organizations including local First Nations band councils. Future freight strategies will coordinate with port authorities like Harbour Commission of Quebec and logistics companies to optimize supply chains to markets including Toronto and New York City.
