What is the significance of these numbers:

45, 100, 131, 132, 159, 171, 179, 197, 221, 505

UPDATE: It took a day, but two of you (plam and Kaycee) got it within minutes of each other: These are STM bus routes that end at a métro station and share the same name.

From contributor and transit geek Shanake Seneviratne:

The practice of placing a bus route's ultimate terminus on the destination sign is not one that has been adopted by the STM. Unlike other systems that indicate the endpoints of a route (Laval, Longueuil, Ottawa, and Toronto all do good jobs with their destination signs), Montreal has adopted a "dominant street or neighbourhood" naming policy. While this works well in principle, in actual fact this can backfire. The 168, for example, hasn't served Cité du Havre proper in decades. The 460 doesn't go on the Métropolitaine but rather parallel to it. The 215 is more deserving of the title Brunswick than the 208 is!

With new buses with excellent capabilities with regard to their destination sign, the STM can surely be more flexible and proactive.

Of course, most of these buses are actually named for the streets that the métro stations are named after, but there's an interesting debate on what names bus routes should take.

Maybe it's just because I'm so used to the Montreal system, but I tend to like it for the most part. It runs into trouble when routes don't take any particular street for very long. Naming buses for their destination assumes that people are going to that destination. While métro stations and terminuses are certainly big draws for transit users, they're not the destination for all.

Besides, with maps at most bus stops now, and the increasing use of smartphones to get information on the go, the importance of the name of a bus route has diminished.

What is the significance of the shaded area of this map?

UPDATE: COOL FAT MICHAEL FROM THE JERSEY SHORE ‘87 and Jim both got the right answer: these are the borders of the village, town, city and ward of Sainte-Cunégonde, sandwiched between St. Henri (whose eastern border was Atwater) and Montreal.

Not only was this independent city tiny (in 1840 it had 10 inhabitants), it was also short-lived. It was developed after it was bought by Alexandre Delisle and William Workman around 1850. At first, it relied heavily on bordering St. Henri for basic services like schools and a church, but the village's inhabitants, upset with the distance they'd have to travel and the taxes they'd have to pay, wanted some of their own.

Ste. Cunégonde was founded as a parish in 1875, taking its name from Cunégonde de Luxembourg. It was incorporated in 1887 and became its own city in 1890.

But around the turn of the century, Ste. Cunégonde faced the same fate as many other towns around Montreal at the time: merger. In 1905 it became a ward of the city of Montreal. By the midpoint of the 20th century, the boundaries ceased to have any meaning.

Today, the only remnants of the town are the buildings (including the old Sainte-Cunégonde church, now the Korean Catholic Mission on St. Jacques), and the street and park named after it.

For more on the village, you can read this book, published in 1893 by E.Z. Massicotte.

This week's trivia question comes from Clément Côté, who submitted this photo:

Where is this?

UPDATE: Enough of you are on the right track that I'll give it to you: It's part of the locks at Côte St. Paul. Côté provided a couple more pictures for context:

In Quebec, every named street has an official designation, comprising of a generic (Rue, Chemin, Boulevard, Avenue, Ruelle, Croissant, etc.) and a specific (de Maisonneuve, Sainte-Catherine, René-Lévesque). On signs in Montreal, the specifics are written in large letters and the generic in smaller letters on top.

Where there is no generic, or street type, the default is "Rue", or "Street".

There is an exception to this, a named road that has no small type on its street signs (old and new), but that isn't a "Rue".

What is it? And what type of street is it?

UPDATE: Couldn't fool you folks. A bunch of you got it right, but once again COOL FAT MICHAEL 1999 FROM DIRTY JERZY was first: It's Le Boulevard.

Le Boulevard in Montreal

But it's also The Boulevard, depending on the sign:

Another sign at the same intersection, only now it's "The Boulevard"

And, in case it was ever in doubt, Le Boulevard is officially classified as a boulevard. Though calling it "Boulevard Le Boulevard" would be incorrect.

Similar exceptions in other towns in Quebec are stranger than that. In St. Jérôme, there's 1er Boulevard, 2e Boulevard up to 5e Boulevard, but those are classified as streets, as are Grand Boulevard in Ile Perrot, St. Bruno and St. Hubert.

This week's question based off a suggestion from Jean Naimard:

What is this a somewhat-stylized photo of?

UPDATE: A few of you guessed a cemetery, but COOL FAT MICHAEL 1999 FROM DIRTY JERZY was the first to correctly name it: It's the entrance to the Mount Royal Funeral Complex, at the end of the chemin de la forêt in Outremont.

What is this blob in the shape of?

UPDATE: This week's winner is "COOL FAT MICHAEL 1999 FROM DIRTY JERZY", who correctly guesses that it's "That bay/inlet thing of Lac St Louis near Pointe-Claire where Pine Park Beach is, by Bayview Hospital."

In other words, Valois Bay in Pointe-Claire.

Another suggestion from a reader: Where in Montreal do a street ("rue") and avenue of the same name intersect?

Bonus half-points if you want to throw in streets and crescents, streets and boulevards, streets and terrasses, etc., which are much more common.

Alexandra Avenue and Alexandra Street

UPDATE: I should have excluded numbered streets and avenues (too easy). The answer I (and contributor Jean Naimard) had in mind was Alexandra St. and Alexandra Ave. in Little Italy. But I'm sure you can come up with others.

What is this?

UPDATE: Wow, this one took a full 14 hours. Jean Naimard gets it right, it's Belvedere Rd. in Westmount. At the top is where it intersects Côte des Neiges, then winding its way up the mountain, making an odd U-turn and heading down to terminate at The Boulevard.
