QC: Autoroute 19
« on: July 19, 2019, 07:57:42 pm »
I was looking over the Québec Atlas des transports and it has A-19 ending at the BoulHenBou point; the rest of it to A-40 is labeled as reference route 61190.  Signage in the field matches this.

Thanks, especially for the link to Atlas des Transports, which looks like a useful resource I'll have to play with when I have more time.

Changes to A-19 made in my local files. In my queue to be pulled in along with some non-Quebec changes.

A-19 edited, in the HB.

I've started looking at other Autoroutes supposedly with urban at-grade intersections, to see if Transports Quebec is truncating Autoroutes to remove those intersections. It looks like that happened with A-740 in Quebec city, with its south end crossing the Laval University campus. The Atlas des Transports and GMSV show that A-740's south end is at Boul. Hochelaga, one block north of QC 175 where the HB now has the south end.

The A-740 point on QC 175 would need to be renamed, probably to AutRobBou since the street name at the QC 175 intersection seems to be Autoroute Robert-Bourassa (who, BTW, is unrelated to Henri Bourassa) even if it's not part of A-740 at QC 175.

I'll keep looking for more needed changes, before pulling in changes to A-740 and QC 175.

That reminds me, I forgot to mention A-10.  The surface roads where the viaduct was removed are part of reference route 60110, with A-10 starting at Rue Wellington.

What about the tunnels and ramps between A-720 and the removed viaduct, that seem to have once been part of A-10? Those seem to be part of an Autoroute, but I can't tell whether it is A-10 (which would mean a route split) or A-720 (which is doomed as an Autoroute, anyway).

Also, I couldn't find an I-10 Fin sign in GMSV to visually confirm the truncation, as we found for A-19 and A-740. Maybe too soon after demolition of the viaduct, for such signage to be erected or to show up in GMSV.

Those show as ramps of A-720, which they might have always been.  Old signage from street view suggests that the historic end of A-10 was Rue Notre Dame instead of A-720; that's where the A-10 Fin sign was.  A-720 was signed as an unnumbered exit.

A-19 is a strange case. It is fully posted down to A-40, but it officially ends where the freeway ends.

Signage for A-10 disappears at the first signal. I drove that multiple times the weekend of the MTL meet.

Is it really, though?  The only signs I saw in street view that were ambiguous were the ones at the A-40 "interchange" itself.  The other ones had directional arrows underneath, indicating that you're not on A-19, as otherwise they'd be reassurance shields.  Note that Québec does not use "TO" banners or an equivalent at all, so that is their method of signing a situation where literally we would (and on freeways they just sign them the same as intersecting routes, making it impossible to determine 100% where a route is from the A-40 signs alone).

Inteststing... and right after the "A-19 Fin" sign on the freeway, too!  I wonder if it was signed at one time and then the province decided to truncate it, but the city didn't bother to change it's signs?  Making things even more interesting, I found another "A-19 Fin" sign nearly a whole km north of A-40!

I agree with Val that the signs at A-40, and on Ave. Papineau, only point you toward A-19 rather than show that A-19 extends south of Boul. Henri-Bourassa. Quebec's not using Vers (to) signs confuses things.

My first experience with the vagaries of Autoroute signage, CHM had A-640's east end at QC 138, which had signage like that on A-19 pointing toward the Autoroute. Only the FIN sign was (and still is, per May 2019 GMSV) at Ch. St-Charles (QC 344), which is the first at-grade intersection south of A-40. Tim agreed we should truncate A-640 to where the FIN sign was.

I would leave A-19 as is, after the truncation to Boul. Henri-Bourassa.

BTW, I'm still checking other Autoroute ends, to look for truncations beside the one at the south end of A-740. I looked at the north end of A-25 in St-Esprit, which in 2017 we extended northward past an at-grade intersection, to the northern junction with QC 125/158. I field-checked that change. Atlas des Transports confirms the change we made. At-grades are OK on rural Autoroutes (several routes have them), even if Transports Quebec avoids them for urban Autoroutes.

Atlas des Transports confirms the change we made. At-grades are OK on rural Autoroutes (several routes have them), even if Transports Quebec avoids them for urban Autoroutes.

A few notes on my check of the remaining Autoroutes:

-- Atlas des Transports shows A-55's north end, and the ends of both A-85 segments, at non-intersection points. Our settled practice, for Quebec and Ontario freeways, is for us to end the route at the last interchange or intersection. I'm leaving those alone.

-- ADT shows the east end of A-440 (West Quebec) one intersection (Ave. St-Sacrament) beyond the signalized at-grade intersection where the HB now places the endpoint. Only all the signage, shown in very recent GMSV, says A-440 ends where we have it. Leaving that alone, except to correct the endpoint label (old label kept and hidden).

-- A-530's west end checks out. I would leave it alone, except for renaming the endpoint for intersecting road Ch. Larouque (keeping and hiding the existing label) for clarity.

-- ADT shows the west end of A-540 at QC 138, where we have it in the HB, even though there's a signalized at-grade intersection to the east at Ave. Jules-Verne. In this case, signage on the ground agrees with the ADT, and supports leaving this one alone.

-- ADT shows A-573's north end at the third at-grade intersection after the freeway ends, which is where the HB now has it. GMSV confirms that's where the FIN sign is, and also by then A-573 is a rural undivided highway. No change needed.

-- A-930 is unchanged, except a label correction for a point not in use.

-- ADT and the HB have the south end of A-955 (a rural Autoroute with lots of at-grade intersections) at RuePri. But the FIN sign is one intersection to the north, at QC 122, and there is no contrary signage to the south. I would truncate to QC 122.

-- ADT shows, and GMSV confirms, that A-973 ends at existing waypoint RueCroRou, rather than the next intersection RueDor where the HB now has the southern end.

I'll assemble a pull request for all the above Autoroute edits, and minor changes to a few provincial routes, tomorrow.

What's interesting is that this sign makes it look like the end is at the first at-grade rather than at the QC 125/158 junction (although there are reassurance shields south of the junction on the portion this sign implies is not part of A-25).

Yeah, I saw an A-25 reassurance marker southbound, north of the traffic signals. Also, shapefiles put the north end where we have it in the HB.
