Quebec Route 117

This description of Route 117 follows it from southeast to northwest.

Route 117 starts in Montreal at the Decarie Interchange where Autoroute 40 and Autoroute 15 (Decarie Expressway) meet. Montrealers sometimes unofficially extend Route 117 along the portion of Decarie Boulevard that runs parallel to the Decarie Expressway.

From the Decarie Interchange, Route 117 goes north on Marcel-Laurin Boulevard to Keller Boulevard. It continues from Laurentian Boulevard to Keller Boulevard, southbound only, or on Lachapelle Street from Keller Boulevard, northbound only, and crosses the Rivière des Prairies over the Lachapelle Bridge to Île Jésus. It continues through the Laval neighborhoods of Chomedey, Fabreville and Sainte-Rose, northbound as Boulevard Curé-Labelle, Boulevard Chomedey at the former Chenoy's deli, left turn at Boulevard Cartier and back into Boulevard Curé-Labelle, southbound as Boulevard Curé-Labelle.

At the Rivière des Mille Îles, it crosses over the Marius Dufresne Bridge to the "North Shore" (of the Rivière des Mille Îles). Then, Route 117 runs parallel to Autoroute 15 until Sainte-Agathe-des-Monts and goes through the Laurentian mountains. Towns along the route in this section include:

After Sainte-Agathe-des-Monts, Route 117 continues as a four-lane divided highway and winds its way through Laurentides Regional County Municipality until it reaches the town of Labelle. From then on to the Ontario border, Route 117 is mostly a standard two-lane highway.

Highway 117 at the Dozois Reservoir

From Grand-Remous, the route heads north for some 220 km (140 mi) through undeveloped wilderness, most of which is part of La Vérendrye Wildlife Reserve. While the reserve is popular for a variety of outdoor activities, services along the road are sparse. This section is often considered one of the most dangerous routes in the province because of numerous fatal accidents, some involving tractor-trailers. During the winter, the route is often extremely slippery, even during dry and clear days. The few communities along this section are:

• Réservoir-Dozois
• Val-d'Or

After the intersection with Route 113, which continues north to Lebel-sur-Quévillon, Route 117 heads west to Ontario where it becomes Highway 66. The section between Rouyn-Noranda and Arntfield runs concurrent with Route 101. Towns along the route in this section include:

• Val-d'Or
• Malartic
• Rivière-Héva
