Closure of René-Lévesque Boulevard South starting Tuesday, December 5

As part of the construction of the new Champlain Bridge, Signature on the Saint Lawrence wishes to inform road users of a long-term disruption on L’Île-des-Sœurs.

Starting Tuesday, December 5, 2017 (5 a.m.) René-Lévesque Boulevard South between Champlain Bridge and the Claude-Robutel Roundabout will be completely closed. René-Lévesque Boulevard North still has one lane open pending a temporary lane that will be open during weekday rush hours during the winter of 2018.

Here are our recommended routes for Pointe Sud and Pointe Nord road users on L’Île-des-Sœurs.

For some weeks now, work has been under way to optimize L’Île-des-Sœurs Boulevard, made necessary by the other work in the area. A traffic light will give Pointe Nord road users access to Hwy-15 South and the Champlain Bridge, whereas some access points near the Place du Commerce Roundabout will be expanded to two lanes. Finally, the STM will benefit from a reserved lane.

Here is a map of the improvements to L’Île-des-Sœurs Boulevard, effective Tuesday, December 5 (5 a.m.):

There will be signs indicating the various detours and police officers will be strategically placed to limit the impact on traffic in the area.
