As of 2025[update], Route 185 is a two-lane highway with passing lanes. Often cited as one of the most dangerous highways in Canada, it is being upgraded to autoroute standards as a four-lane, fully controlled-access highway, assuming and extending the existing Autoroute 85 designation. Several sections have been completed and opened as such. Once this upgrade is completed, it will close the last gap in a continuous freeway section of the Trans-Canada between Renfrew, Ontario, and Lower South River, Nova Scotia, a length of over 1,500 kilometres (930 mi), and for an even longer interprovincial freeway route between Windsor, Ontario, and Halifax, Nova Scotia, via Toronto and Montreal, a length of about 2,150 kilometres (1,340 mi), roughly playing the same role that the old Quebec Route 2 (which Route 185 was formerly part of) played before its renumbering into several roads in the early 1970s.
As of 2025[update], there are two sections of A-85; one from A-20 to just southeast of Saint-Honoré-de-Témiscouata, and the other from Saint-Louis-du-Ha! Ha! to New Brunswick Route 2 at the provincial border in Degelis. But as of 2016[update], Route 185 no longer connects to New Brunswick Route 2 at the provincial border. The opening of the remaining freeway portion in 2026, which will link the segments of A-85, will also mark the end of Route 185.
