The city of Montreal announced Tuesday that for the spring and summer of 2018, Camillien Houde way will be closed to cars as part of a pilot project.
Cars will still be able to access the mountain from the east and west, but won't be able to drive completely across.
Mayor Valerie Plante says it's part of a scheme to reduce car traffic in the city — and she suggests there's more to come.
"It was important for us to send a strong signal that yes, we want to minimize, we want to reduce, all the traffic on the mountain," Plante said. "In the coming weeks and months we'll be proposing other measures."
Under the pilot project, drivers coming from the east will be able to drive to the Smith house, while those coming from the west will have to stop near Beaver Lake.
While the project is on, the STM's No. 11 bus, which uses a section of the mountain pass, will also have to be re-routed.
The city began exploring options for making the roadway safer following the death of 18-year-old Clement Ouimet, a cyclist who was killed last October when he collided with a truck trying to make an illegal left-hand turn.
"I think this is good news to protect Mount Royal and to protect lives because we see that it's not easy for pedestrians and cyclists and as well car drivers," Plante added. "So we had to find a solution and I'm really glad that this morning we made one."
