Autoroute 10 (A-10) is an Autoroute of Quebec in Canada that links greater Montreal to key population centres in Montérégie and Estrie, including Brossard, Saint-Jean-sur-Richelieu, Granby, and Sherbrooke.

The A-10 also provides access to popular winter resorts at Bromont, Owl's Head, Mont Sutton and Mont Orford. Motorists travelling on the A-10 can see eight of nine Monteregian Hills: Mount Royal, Mont Saint-Bruno, Mont Saint-Hilaire, Mont Saint-Grégoire, Mont Rougemont, Mont Yamaska, Mont Shefford and Mont Brome. (The ninth, Mont Mégantic is located beyond the eastern terminus of the autoroute.

At 147 km (91 mi) long, the A-10 is the fourth longest autoroute in Quebec.

Description

The A-10 carries the name Autoroute Bonaventure (Bonaventure Expressway) from its start in Montreal's city centre to the Champlain Bridge. From there until its terminus in Sherbrooke, the A-10 is called the Autoroute des Cantons-de-l'Est (Eastern Townships Expressway), a reference to the historic name given to the region east of Montreal and north of the U.S. border.

The road's main material is asphalt concrete, many parts of the highway are bordered with gravel.

History

The 116 km (72 mi) long Autoroute de l'Est (Eastern Expressway) was opened to traffic in December 1964. Extending from the southern end of the Champlain Bridge to Magog, the highway replaced the old Quebec Route 1 (now Route 112) as the main road link between these two points. An official opening for the highway came one year later, in 1965. The A-10 was the second autoroute, after the Laurentian Autoroute outside Montreal, to be commissioned. Both were opened as toll highways by a Quebec government agency. The A-10 featured five toll stations (at current km 22, km 37, km 68, km 90, and km 115). Motorists were charged $1.50 to make the entire trip.

The Autoroute Bonaventure through Montreal opened in 1967 to link approach roads to Expo 67 with the Champlain Bridge.

The Autoroute des Cantons de l'Est was the first autoroute in Quebec to use exit numbers based on distance instead of in sequential order, as had previously been the case. As Canada had not yet adopted the Metric system, exit numbers referenced the distance in miles from the southern end of the Champlain Bridge.

The A-10 did not originally have a route number. Instead, route marker signs featured a red triangular shield featuring the name of the route. Unusually, the directional signs were also originally red. Later, blue shields and signs replaced the red versions.

In 1985, the toll system was abolished, and the use of the triangular shields were discontinued. Blue directional signs have gradually been converted to standard green signs used elsewhere in North America. In 2013, motorists could still see blue signs at entrances to and exits of the autoroute.

Between 1988 and 2006, A-10 departed its multiplex with A-55 at km 143 and continued eastward for 11 km to a final terminus with Route 112. In October 2006, that section of A-10 was renumbered as A-610.

Future

Under a project started in 2016, the Autoroute Bonaventure will be completely reconfigured by 2018.^[3] The Société du Havre de Montréal (SHM) is transforming the autoroute into an urban thoroughfare as part of a broader project to redevelop Montreal's harbourfront.^[4] The city of Montreal announced in January 2013 that it would take over the SHM's responsibilities, citing concerns over transparency.^[5]

The new Robert Bourassa Park which replaces the elevated structure in Downtown Montreal

A current proposal to build the East-West Highway across central and northern Maine calls for the A-10 to be extended to the U.S. border at Coburn Gore where it would meet the new highway. Doing so would create a new and more direct limited-access highway link between Maine, the Maritime Provinces through New Brunswick Route 1, and Quebec.
