The last section of Autoroute 30 in Quebec opened on December 15, 2012, from Chateauguay to Vaudreuil-Dorion, completing the southern bypass around Montreal, and including a new bridge over the St. Lawrence River; see here, here, and here. Google Maps shows the new highway on the map, but does not yet include it in driving directions. For example, a trip from Beauharnois to Les Cedres should be about 17 km using the new highway 30, but Google still gives a 40-km route, crossing the river much farther west using Route 201.
How long does it usually take for Google to update its driving directions, and what can we do to help?
