using the
Seal Island Bridge. The highway travels northeast from Port Hastings along the base of a group of mountains known as "The Big Ridge" to
Whycocomagh. It then follows the north shore of
Bras d'Or Lake, bypassing
Baddeck on a short
Super two controlled access segment. Still running in a general northeast direction, at
St. Anns the highway begins ascending the west slope of
Kelly's Mountain on the Cape Dauphin Peninsula. Highway 105 descends the east slope of Kelly's Mountain using a series of sharp turns including a 180°
hairpin turn at
New Harris Forks before crossing the Great Bras d'Or Channel of
Bras d'Or Lake on the
Seal Island Bridge. The road crosses
Boularderie Island using another short
Super two controlled access segment and then runs southeast as an uncontrolled access road through the villages of
Bras d'Or and
Florence. Highway 105 regains controlled access for the final to its eastern terminus at the
Marine Atlantic ferry terminal in
North Sydney where travellers can continue to
Newfoundland. With some minor exceptions noted above, the highway is two lanes and uncontrolled access. In addition, there are two intersections controlled by
traffic lights in Florence. The
Cabot Trail, which is usually used to describe a different road, is signed along a portion of Highway 105 between
Nyanza and
St. Anns so that the signed route forms a loop. ==History==
