After crossing a Via Rail line, the route dips south of Casselman and curves to the west at Exit 66 (County Road 7). It roughly parallels the Via Rail line several kilometres north of the freeway, though significant deviations bypass the communities of Benoit and Limoges; the latter is served by Exit 79 (County Road 5). Near Limoges is the Larose Forest, a man-made forest planted between 1928 and 1980 over the Bourget Desert, itself created as the result of clear cutting in the 19th century.
