In spring 2026, work will begin on installing a median guardrail on Autoroute 50 between Scotch Road (Route 344) in Grenville-sur-la-Rouge and one kilometre east of montée Rochon in Brownsburg-Chatham.
On Thursday, November 13, Québec Transport Minister Jonatan Julien, and Regional Minister for the Laurentides Region Sonia Bélanger announced the publication of calls for tenders as part of the Autoroute 50 safety plan.
The installation of a new semi-rigid guardrail in the center of the adjacent lanes on two-lane sections of the highway aims to reduce head-on collisions. This will improve safety over approximately 10 additional kilometers.
“With the installation of this new guardrail, our government reiterates its firm commitment to taking action to reduce the risk of accidents on Autoroute 50. Every kilometre we make safer on this important highway is another step towards a safer road for everyone. Safety will always remain a priority,” Julien said.
In addition to the installation of the semi-rigid steel median barrier, resurfacing work will be carried out in the same area, on a 14-kilometre section.
Two calls for tenders will be issued for the safety improvements on the section between Grenville-sur-la-Rouge and Brownsburg-Chatham, one for professional services and the other for the execution of the work.
The analysis of the adjacent lanes between L’Ange-Gardien and Mirabel continues in order to determine the next steps to improve safety.
In Mirabel, since the beginning of November, road users have had two lanes in each direction for almost the entire distance between chemin Saint-Simon and Mirabel International Airport, at the point where the two carriageways diverge.
Meanwhile, the design and planning phases are continuing for the widening of the section between Route 329 in Lachute and chemin Saint-Simon in Mirabel.
The work to widen Autoroute 50 between Gatineau and L’Ange-Gardien was completed in 2024.
