QUEBEC CITY—A “major artery” of Quebec City’s road network is undergoing a $291 million facelift.

The project to widen and repair Henri-IV Highway from Charest Highway to Chauveau Avenue broke ground August 8 in the province’s Capital Region.

Ottawa has contributed $128 million to refurbish the road. Initially estimated to cost between $400 and $500 million, the federal government scaled back the $173.6 million in funding it allotted in September 2017.

The highway will be widened to three lanes, in both directions, between the Charest (440) and Félix‑Leclerc (40) highways. That stretch of road will also be repaved.

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.

Related infrastructure, such as overhead signage, drainage and lighting, will also undergo repairs. Geometric changes will be implemented to certain on‑ and off‑ramps, intended to lengthen merge lanes.

Upgrades to the more than 50-year-old highway began gradually in July and will continue until 2023.
