The governments of Canada and Quebec are working together in the Capitale Nationale region to improve traffic flow for citizens, maintain existing infrastructure make the road network more efficient and improve road safety to meet current and future transportation needs.

“I am very pleased to take part in this event marking the start of work on widening the Henri-IV Highway. Investments like this make up our commitment to a historic infrastructure plan that will not only create jobs and new opportunities for the middle class, but will also lay the groundwork for sustainable, long-term economic growth. Through this plan, we are helping to build strong, resilient and inclusive communities that will remain competitive in this 21st‑century economy and be successful for generations to come.”

The Honourable François‑Philippe Champagne, Minister of Infrastructure and Communities

“I am delighted to mark this important chapter for the Henri‑IV Highway, which will modernize key transportation infrastructure in the Capitale‑Nationale region. This work will help extend the life of the highway and reduce long‑term maintenance costs. Once completed, this project will make it easier for users to travel safely so they can spend more time with their families.”

The Honourable Jean‑Yves Duclos, Minister of Families, Children and Social Development and MP for Québec City

“Built in the 60s and 70s, this highway was in dire need of a facelift. I am thrilled to see the work take off. This project shows that our government is steadfastly focused on the future. The improvements made over the next few years will significantly improve the fluidity of this vital corridor and the region as a whole.” 

Véronyque Tremblay, Minister for Transport

“Capitale‑Nationale residents will be reassured to see the efforts being made by this government to improve their mobility, safety and quality of life. With the new developments, the sector’s strategic road network will be more efficient. Every effort will be made to limit the impacts of this work on traffic until the project is complete” 

Sébastien Proulx, Minister of Education, Recreation and Sports and Minister Responsible for the Capitale‑Nationale Region

"The launch of work on the widening of the Henri-IV highway is the result of a commitment we made to the people of Quebec City to improve the flow of traffic in the north-south direction. This major artery of the regional road network dates back over 50 years and the achievement of this commitment responds to a major mobility issue for our city. "

Marie‑Josée Savard, Councillor for the Cap‑Rouge–Laurentien District and Vice‑Chair of Québec City’s Executive Committee

• More than 100,000 vehicles use the Henri‑IV Highway every day. 

• The project involves widening the Henri‑IV Highway to three lanes, in both directions, between the Charest (440) and Félix‑Leclerc (40) highways. A three‑lane northbound extension will also be constructed for the portion between the Félix‑Leclerc (40) Highway and Chauveau Avenue, to the city limits of L'Ancienne‑Lorette.

• The project includes:

  • Repaving the roadway between the Charest and Félix‑Leclerc highways
  • Work on all structures, including 13 that will undergo major work;
  • Repairs to all infrastructure (roadway, overhead signage, drainage and lighting); and,
  • Geometric changes to certain on‑ and off‑ramps, mainly to lengthen merge lanes for greater safety and better flow.

• A number of measures will be taken throughout the project to limit the impacts on the quality of life of area residents and road users, including:

  • temporary adjustments (slip lanes, curb lanes) to make travel easier;
  • use of the shoulder by Réseau de transport de la Capitale (RTC) buses on the Henri‑IV Highway southbound, between Sainte‑Geneviève Road and the Félix‑Leclerc Highway;
  • use of variable message signs to inform users of traffic conditions and congestion;
  • ongoing coordination with partners, including Ville de Québec, the RTC and police forces; and,
  • measures to minimize noise at night, including a noise monitoring and control program

• Through the Investing in Canada infrastructure plan, the Government of Canada will invest more than $180 billion over 12 years in public transit projects, green infrastructure, social infrastructure, trade and transportation routes, and Canada’s rural and northern communities. More than $10.1 billion of this funding will support trade and transportation projects, including $5 billion that will be available for investment through the Canada Infrastructure Bank.
