It is a section of Quebec Route 134 and runs from Longueuil to Candiac (junction of Autoroute 15).

It is named after the prominent Quebec family, which included former premier Louis-Alexandre Taschereau.

In some sections, it is designed as a right-in/right-out expressway with at-grade intersections on the municipality-maintained (usually right) line to local streets from one side of the highway.

[1] At the intersection of Taschereau Boulevard and Autoroute 10 (45°27′54″N 73°27′58″W / 45.464917°N 73.466134°W / 45.464917; -73.466134), a construction project was undertaken in 2002 to reorganize the entry and exit ramps.

[needs update] This project also intends to allow the traffic to pass through the centre of the interchange, to reduce noise pollution through sound barriers, to allow a bus lane (and later a light railway transit system) to access RTL bus terminals without affecting highway or road traffic.
