Route 137 Route 139

Route 138 is a major highway in the Canadian province of Quebec, following the entire north shore of the Saint Lawrence River past Montreal to the eastern terminus in Kegashka on the Gulf of Saint Lawrence. The western terminus is in Elgin, at the border with New York State south-west of Montreal (connecting with New York State Route 30 at the Trout River Border Crossing). Part of this highway is known as the Chemin du Roy, or King's Highway, which is one of the oldest highways in Canada.

It passes through the Montérégie, Lanaudière, Mauricie, Capitale-Nationale and Côte-Nord regions of Quebec. In Montreal, Highway 138 runs via Sherbrooke Street, crosses the Pierre Le Gardeur Bridge to Charlemagne and remains a four-lane road until exiting Repentigny.

This highway takes a more scenic route than the more direct Autoroute 40 between Montreal and Quebec City. It crosses the Saguenay River via a ferry which travels between Baie-Sainte-Catherine and Tadoussac.

Until the mid-1990s, the highway's eastern terminus was Havre-Saint-Pierre, but in 1996 the extension to Natashquan was completed. A 40km section between Natashquan and Kegashka opened on September 26, 2013, with the inauguration of a bridge across the Natashquan River.[2][3]

A second segment of Route 138 extends from Old Fort to Blanc-Sablon on the eastern end of the Côte-Nord.[4]

A gap remains between Kegashka and Old Fort, through isolated communities accessible only by coastal ferry. On August 25, 2006, the Quebec government announced a 10-year project to connect the two segments by building 425 km of highway along the Lower North Shore.[5]
