Quebec Autoroute 70

Quebec Autoroute 70

Autoroute 70, or A-70, is a short Autoroute located in the Saguenay-Lac-Saint-Jean region of northern Quebec. It is currently the only Autoroute that does not connect to any other Autoroutes, although other Autoroutes currently have discontiguous segments such as A-20 and A-30, as well as an isolated indigenous network of ones near the Quebec side of metropolitan Ottawa, Ontario. A-70 was first created in 1983, and has since been extended three times.

A-70 is currently 27 km (16.8 mi) long, however extensions are planned in both directions. A-70 is only partially completed; currently it acts primarily as a bypass route around the urban area of Saguenay. The route was slow to develop; until 2001 it was an extremely short stub, less than 6 km (3.7 mi) long.

It is expected that A-70 will be extended westward to at least Alma and eastward to La Baie. A new alignment has already been determined for the westernmost section of A-70, and the central section (currently part of Route 170) is already a 4-lane divided highway; service roads would need to be constructed as it is not limited access. The proposed route for the eastern section has also been determined.

The ultimate length of A-70 will likely be around 64 km (39.8 mi) in length.
