Seasonal closures affect not only seasonal road closures (mountain passes and the like) but also closures due to roadworks. This is why the route takes you through the closure even during planning, even though Here is actually aware of it.

Chances are that when you use offline navigation the app works like the web based planner. But thats not what you want.

My issue related to closures is in the app. How the app guides me through or around a closure seems to depend on:

1. using online or offline maps/navigation
2. which Navigate button I press (the other one is in the inapp-routeeditor)
3. navigating a route as track or as route.

I can understand 1 (when closures are recent and only available online) but not 2 and 3. I see this happening, even when I only use the app the make and navigate the route.

This is know, and have never experienced it as a problem. It's actually nice to be able to disable a road closure when you see it is not there (anymore).

[Herman Veldhuizen]

@Con-Hennekens Do you have a link to some documentation if this is known? I searched and havent found it

[Con Hennekens]

@Herman-Veldhuizen, No I don't. But I have noticed before that disabling seasonal closures often leads to roadworks not being detoured. I think in the end a seasonal closure is a road closure too.

@Herman-Veldhuizen & @peter-zehentreiter this is known functionality & can actually be quite useful
using the seasonal closure function has been recomended on this forum as an answer to actually enabling you to plan a route today through a closure, that you expect to be gone in a few weeks or months

the term "seasonal" is unfortunatley a bit missleading as the function really ignores a lot of closures
the term "seasonal" is probably a historical thing thats never been updated on the web planner

if you search the forum for "seasonal closure" I am sure you will find this is not new

[Herman Veldhuizen]

@Brian-McG That the setting for seasonal closures can effect regural closures too is one thing. The fact that there are inconsistencies between the web and the app and in the app itself is another thing.
For example: When I make a route I spent most time in the inapp route editor (not the web based one) and expect the blue line which I see there to be the same when I press Navigate directly after. This wasn't the case when I last tried it.

As mentioned, blocked roads aren't always reported. For example, in this case, myrouteapp web doesn't correctly let you pass through the blocked road:

This winter, there were heavy rains and many landslides, with roads closed for a short time or unfortunately for a long time, depending on the severity. So, when I plan a route this year, I first quickly trace it using Google Maps, which is generally much more accurate than myrouteapp when it comes to closed roads. Then, I recreate it in myrouteapp, making any necessary adjustments.

Earlier this year I was trying to plot a route in the UK Peak District and MRA would NOT let me set a route through a particular village. Then, a day or so later, it would, and then later again still not. I realised afterwards that there were temporary roadworks that were probably being opened/closed almost daily. This was confirmed when I rode the route and had to go back the way I had come a short distance to take a diversion.

The last couple of days I have also been working on a route for the passes in the Lake District. Kirkstone Pass has, I think, been closed for repairs but was recently re-opened. However, MRA would not let my route go down the southern end, between the Kirkstone Pass Inn and Troutbeck. Instead, it sent the route around through Ambleside.

At least, it did until I toggled the Seasonal Closures option on/off, after which it's now happy to go down the correct way. It wasn't a seasonal closure so I'm not sure why that worked, but it seems to have sorted it.

Something which may help is this website: in their own words "Causeway one.network is a platform that Highway Authorities, Utilities, and Contractors use to communicate roadworks." https://one.network/en-gb

it's scrollable, zoomable and shows different icons for the type of work being done. Coverage seems to be England, Scotland, Wales and the Isle of Man but not Ireland.

I can't guarantee how up to date and accurate it is and I don't think they can either, as the data comes from the different road contractors, but it may help someone.

I do not see the difference in handling a road closure between teh Route Planner and the Navigator to be a big issue.
You may be planning a route today to be used sometime in the future or today or tomorrow... Route planner does not know when you will actually use it.
When you start navigating, it is a real-time situation and I assume that is why you are offered a roadblock bypass.
I did not test the following: I wonder what would happen if in the Route Planner you set up the departure date to be when the road is actually closed. Would it stop you from using it....???

[Carl Lee]

Not the perfect MRA answer but I often save a GPX1.1 (track) to Google maps on my PC to build a route on there. If you then enable Traffic, you get all the details with timings too.

How about just renaming it 'Disable road closure routing'?

Then it covers all bases, and is less confusing to lowlanders like us English and the Dutch!

[John S Parry]

@richtea999 If a road is flagged by HERE as having a seasonal closure any time of the year, you have to check "Disable seasonal closures" to route through it -- even if the closure is for winter only and it's currently the dead of summer. Logically, it should only apply when the road is actually seasonably closed, and you want to create a route through it for future use.

There is a good forum discussion on the confusion surrounding this Toolkit routing option avoidance:

https://forum.myrouteapp.com/topic/5608/seasonal-closures-app-versus-planner-problem

The obvious (to me) option would be to have an "Ignore Closed Roads" option for creating routes, regardless of what the immediate real-time situation is. Let me decide what's passable, and what isn't. Google will always be a better investigative solution than HERE, so let me do my own research. I've suggested this before, but for whatever reason it's been ignored by the powers that be.
