A-20 (Quebec)

Hitching the A-20
{{legend}}

The A-20, known as Autoroute 20 and officially named Autoroute Jean-Lesage is one of the oldest highway infrastructure of Canada. You might indeed notice it when transiting through this major way that connects Montreal to Quebec city by the south shore of the St-Lawrence river further West becoming the H-401 in Ontario towards Toronto and stretching further East into Gaspesia and nearly connecting New Brunswick which can be reached by continuing on the Route 185 and becomes the Route 2 in New Brunswick.

The A-20 is part of the Transcanadian Highway in nearly all of its length with exception of the part West of Montreal.

In Monteregie and Montreal Metropolitan
While in Montreal and Montreal Metropolitan leaving the area, the A-20 connects on Monteregie Island with the A-40 by taking either the A-13 - A-15 or A-25 northwards for a few km. Around the International Airport of Dorval, the Autoroute Cote de Liesse (A-520) act as a connector between the A-20, the international airport and the A-40.

It also crosses the path of other major highways such as the A-10 towards the Estrie Townships and the A-30 which act as a By-Pass to the Southern Montreal Metropolitan (In Construction). The A-20 crosses officially the St-Lawrence onto Montreal on the 'Pont Champlain' together with the A-10 and the A-15. Although the 'Lafontaine Tunnel' marks the end of the A-25 to become the A-20 Westbound and the 'Pont Jacques-Cartier' as well as the 'Pont Victoria' goes direct from the A-20 on the St-Lawrence South Shore to downtown Montreal.

In Montérégie, Centre-du-Québec and Chaudière-Appalaches
From Montreal Metropolitan South shore, the A-20 heads eastwards crossing many localities of this vast farmland region. It reaches the junction of the A-55 (coming from the South (Sherbrooke) at Junction 173) just west of Drummondville. The A-55 and A-20 overlap on the same infrastructure for about 30km before it heads back north towards Trois-Rivières from Junction 210.

In Chaudière-Appalaches and Bas-St-Laurent
The A-20 does not get into Quebec city but instead goes along its St-Lawrence southern shore sister city Levis. Just west in the vicnity of Levis there are major off the motorway services with restaurants at Exit 311 and Exit 314. Note that Exit 312 is the motorway junction with the A-73 to cross the St-Lawrence north into Quebec city (through Pierre-Laporte bridge or alternatively through Quebec bridge) or south towards Maine. Bear in mind that Exit 314 also leads to 'Quebec Bridge' which can be crossed by foot.

Further east, the A-20 continues just south of Levis eastwards in direction of New Brunswick and Rimouski.
