Autoroute 25 (orA-25, also calledAutoroute Louis-H.-La Fontaine inMontreal) is anAutoroute in theLanaudière region ofQuebec. It is currently 49 km (30.4 mi) long and services the direct north of Montreal's Metropolitan Area. A-25 has one toll bridge, which is the first modern toll in the Montreal area and one of two overall in Quebec (after being joined by the A-30 toll bridge, which opened in 2012).
A-25 begins at an interchange withA-20 andRoute 132 inLongueuil and quickly enters theLouis Hippolyte Lafontaine Bridge-Tunnel into the east end of Montreal. It is the main north-southfreeway in the east end of Montreal (actually northwest-southeast but perpendicular to theSt. Lawrence River).
Before the Montreal-Laval Extension, a gap existed in A-25 north of the interchange withAutoroute 40. Instead it followedBoulevard Henri-Bourassa toBoulevard Pie-IX, both of which are principal urban arterial roads. Boulevard Pie-IX north of Boulevard Henri-Bourassa was used as a temporary section of Autoroute 25 across theRivière-des-Prairies toAutoroute 440. From there, A-25 proceeded east with A-440, then continued north and east of Laval.
The designation of Autoroute Louis-Hippolyte-Lafontaine is named afterLouis Hippolyte Lafontaine, a 19th-centuryLower Canada leader of what was then theProvince of Canada.
A-25 is also part of theTrans-Canada Highway between the A-20 and A-40 interchanges.

Autoroute 25 has been extended under apublic-private partnership. The 7.2 km section of highway joins the southern part of Autoroute 25 atBoulevard Henri-Bourassa inMontreal's East end and the northern part atLaval'sAutoroute 440. The $207-million project will save some $226 million for the province since a private consortium will assume any cost overruns. Atoll bridge using aRFIDtransponderautomatic payment system spans theRivière des Prairies and costs transponder-owning motorists $3.20 per crossing at peak hours (6-9 AM and 3-6 PM) and $2.24 per crossing the rest of the day. An additional $5.34 in administration fees is charged for motorists without transponders. The road opened on May 21, 2011. The highway has six lanes (three in each direction), while the bridge features three lanes in each direction with one reserved for public transit.
Now that the link between Montreal and Laval is complete, the temporary autoroute section connecting Boulevard Pie-IX toAutoroute 440 lost its A-25 designation. The new route designation for this section isRoute 125.
The new span effectively joins theNorth Shore, Laval, Montreal, and theSouth Shore.
Environmental organizations have raised concerns that the highway extension will lead to an influx of automobiles entering Montreal and increase development pressure on agricultural land in Eastern Laval.[4][5]
