Autoroute 20 is a Quebec Autoroute, following the Saint Lawrence River through one of the more densely populated parts of Canada, with its central section forming the main route of the Trans-Canada Highway from the A-25 interchange to the A-85 interchange. At 548 km (340.5 mi), it is the longest Autoroute in Quebec. It is one of two main links between Montreal and Quebec City; the other is the A-40.
There are two sections of the A-20, separated by a 72 km (44.7 mi) gap that was to be filled in by 2015 according to the Quebec government's Bas-Saint-Laurent plan. The length of the A-20 would then be 641 km (398 mi). Currently, there is no official plan to continue construction past Trois-Pistoles, which will leave a 50 km (31 mi) gap.

Autoroute du Souvenir
The A-20 begins at the Ontario-Quebec border near Rivière-Beaudette as the continuation of Ontario Highway 401. The westernmost section of the A-20 was named the Autoroute du Souvenir (Remembrance Highway) in 2007 to honour Canadian veterans. Road marker signs on this stretch of the autoroute feature a poppy (a traditional symbol of Remembrance in Canada).
At km 29, the A-20 crosses A-30 (former A-540) before becoming an urban boulevard for approximately eight kilometers (km 30 to 38) in Vaudreuil-Dorion and L'Île-Perrot. This stretch of highway takes the A-20 across the Ottawa River. The speed limit is 50 km/h (30 mph) in Vaudreuil-Dorion and 70 km/h (45 mph) in L'Île-Perrot. The A-20 once again becomes an limited-access highway at km 38, just before crossing the Sainte-Anne-de-Bellevue Canal onto the Island of Montreal.
The A-20 then traverses the West Island (in French, l'Ouest de l'Île) along the north shore of Lac Saint-Louis to an interchange with the A-520. Commonly called the Dorval Interchange, this exit is the main access to Montreal's Trudeau International Airport. Further east, the A-20 crosses the A-13 at its southern terminus, and then, at the St. Pierre Interchange, Route 138 west towards the Mercier Bridge.
Just west of downtown Montreal, the A-20, A-15, and A-720 meet at the Turcot Interchange. From this interchange, A-15 continues north to Laval while A-20 east is multiplexed with A-15 south on the approach to the Champlain Bridge. Traffic bound for the city centre continues as the A-720 (Autoroute Ville-Marie).
Between Route 138 and the Turcot Interchange, the carriageways on Autoroute 20 are reversed, making it one of the few stretches of roadway in Canada where traffic drives on the left side of the road.
Multiplexed with the A-10 and A-15, all three autoroutes cross the Saint Lawrence River via the Champlain Bridge to the South Shore (in French, Rive Sud). The multiplex splits south of the bridge. The A-20 parallels the south shore of the river through suburban Longueuil. The junction with the A-25 affords a direct connection to the Louis Hippolyte Lafontaine Bridge-Tunnel and Montreal's East End. The Trans-Canada Highway joins the A-20 at this junction.
The largest section of the A-20 (from its junction with A-25 to its easternmost terminus) is named after Jean Lesage, who served as Premier of Quebec from 1960 to 1966, during the Quiet Revolution. Autoroute Jean-Lesage currently exists as two discontinuous sections separated by about 76 kilometers:
- The main section between the Louis-Hippolyte-Lafontaine Bridge-Tunnel and Isle-Verte in the Bas-Saint-Laurent region.
- A shorter section that serves as a bypass of Rimouski and extends east to a final terminus at Route 132 in Mont-Joli.
From the junction with A-25, the A-20 travels east, away from the St. Lawrence River. At kilometer 98, the A-20 intersects the A-30 near Mont Saint-Bruno, crossing the Richelieu River (km 112) just north of Mont-Saint-Hilaire. Bypassing Saint-Hyacinthe, the A-20 forms a multiplex with Route 116 for six kilometers between exits 141 and 147. This section of the A-20 in Centre-du-Québec is located the furthest from the St. Lawrence River (approximately 45 kilometers). Between Drummondville and Sainte-Eulalie, the A-20 forms a multiplex with A-55 for 37 kilometers.
The A-20 continues across the St. Lawrence Lowlands and Quebec's agricultural heartland. The autoroute once again parallels the river as it approaches metropolitan Quebec City. From this point eastward, the A-20 is never more than five kilometers from the river. At km 312, the A-20 crosses the A-73, a north-south link between Saint-Georges and Quebec City via the Pierre Laporte Bridge. While the control city on the A-20 is listed as "Québec", the autoroute never enters the city proper. Before departing the region the A-20 bypasses suburban Lévis.
This section of the A-20 offers the motorist splendid views over the St. Lawrence River and the mountains of the Côte-Nord, especially Mont-Sainte-Anne and Le Massif. As it continues eastward, the A-20 passes the regional centres of Montmagny and La Pocatière before approaching Rivière-du-Loup and the junction with A-85 at km 499. The Trans-Canada Highway departs the A-20 at this interchange and travels south on A-85 toward Edmundston, New Brunswick and the Maritime Provinces. The eastern end of the main section of the A-20 is located in L'Isle-Verte, approximately 20 kilometres east of Rivière-du-Loup.
The second section of Autoroute Jean-Lesage (km 597 to km 641) connects Rimouski to Mont-Joli. It begins at a junction with Route 132 in the village of Le Bic, approximately 75 km from the current terminus of the A-20 main section. Like its larger counterpart, the Rimouski section of the A-20 parallels the St. Lawrence, providing a southern bypass of Rimouski before ending (at another junction with Route 132) at the western approach to Mont-Joli.
This section of the A-20 is currently a single carriageway with occasional passing lanes. It was built to accommodate an eventual expansion to four lanes and most overpasses include the clearance needed to accommodate the additional lanes. Given the low annual daily traffic rate along this section of A-20, there are no plans for the highway to be expanded.
An electric fence has been installed on both sides of the highway between km 621 and 628 to prevent moose from crossing the road, while at km 624 an underpass has been constructed to allow wildlife to cross safely.
Transports Québec (MTQ) is currently engaged in several projects designed to connect the two segments of the A-20 as well as replace outdated sections.
The MTQ plans to rebuild A-20 (currently an urban boulevard) through Vaudreuil-Dorion and Île-Perrot as a limited-access highway. In Montréal, the MTQ plans to shift the autoroute north between Route 138 and the Turcot Interchange.
Long-range plans by the MTQ call for the two sections of the A-20 to meet. A 9.8 km section of single carriageway was opened to traffic on December 3, 2011 between Cacouna and L'Isle-Verte. As part of this project, a few kilometers of the highway near Cacouna was moved 1.5 km to the south and the old roadbed was destroyed. The MTQ timeline for completing the highway to Trois-Pistoles is December 2015. Overpasses are under construction for the St-Paul, St-Éloi and Drapeau roads. Regarding the Trois-Pistoles-Le Bic section, an environmental impact study is underway.
Autoroute 20 serves as the backdrop to the popular 2002 Quebec film Québec-Montréal by Ricardo Trogi about seven twenty-something travellers driving between the two cities.
