This very short Autoroute is listed in the Autoroute Sytem database. It is about 1 kilometres long. It links A-20 (former future
A-430) to R-134 (former future A-19), thus Jacques-Cartier Bridge and Sir-Wilfrid-Laurier Boulevard.
Its speed limit is exceptionnaly low for a grade-separated freeway, because of narrow 1-lane interchange curves.
