The Eastern section includes a 12.2 km four-lane divided highway south of Candiac, Delson, and Saint-Constant. This section begins at the existing Autoroute 30 in Châteauguay, and extends to the Jean-Leman interchange in Candiac. It will make it possible to reach the existing Autoroute 30 in complete safety.
The Eastern section will not be connected to the local network. However, all of the roads that cross the highway will be maintained through the use of overpasses, but no interchanges are planned in order to limit urban sprawl, among other things.
Jean-Leman Segment in the Eastern SectionThis section of the four-lane divided highway is 3.4 km long (included in the 12.2 km of the Eastern Section), and is not connected to the local road network.
