The governments of Canada and Quebec are set to make a major investment to widen the Autoroute Henri-IV road, as well as refurbish the pavement between the Charest/Henri-IV and Félix-Leclerc/Henri-IV interchanges.  

Autoroute Henri-IV widening project also includes carrying out geometric modifications to certain highway junctions to improve safety and traffic flow.  

A retention basin will also be constructed in the Félix-Leclerc/Henri-IV interchange.

Works are expected to begin next year and the project is estimated to cost between C$400m ($319m) and C$500m ($399m).

For this project, the Canadian Government will provide C$173.6m ($138.8m) and the remaining amount will be financed by Quebec.

"This major project will accommodate current and future transportation demands for users."

Quebec Minister of Transport, Sustainable Mobility and Transport Electrification, Laurent Lessard said: "Autoroute Henri-IV is a key link in the transportation network and it is essential to ensure it lasts while improving the efficiency of this strategic network.

"This major project will accommodate current and future transportation demands for users."

Upon completion, Autoroute Henri-IV will feature three lanes in each direction between Autoroute Charest and Autoroute Félix-Leclerc, spanning 2km.

In addition, a three-lane northbound extension will be constructed for the 1km section between Autoroute Félix-Leclerc and Avenue Chauveau to the city limits of L'Ancienne-Lorette.

The upgrade is expected to improve mobility in the region, as well as extend the life of Autoroute Henri-IV and reduce long-term maintenance costs.
