Add the option for a editor imposed, really heavy penalty to be applied to segments for when a road is technically passable, so we don't want to use a RTC, but it should really be avoided by the routing system and drivers unless absolutely needed.
Examples include construction resulting in a 1-way road.
Construction resulting in a road that's not really fit for driving most cars on, even if the town/state has left it open for travel
Accidents that cause multi-lane closures but traffic is allowed to slowly creep by.

This would be best implemented in real-time like closures are.

I would expect this information to come from the users as well as government entities that are planning road closures. An expected end date could come from the government; it misght be too distracting for the end users to enter it.

I should also add "and off route".

I passed a ramp closure on my way to a small town in Ne. Couldn't mark it because it wasn't part of my route. After my delivery Waze told me to go straight through it. That route would have cost me a 20 mile turn around just so I could inform Wsze of the closure. There were also 2 long term construction projects in my home town that kept opening back up prematurely. If we could mark closures before we see them this would no longer be a point of frustration. Right now there are TONS of bridges out all over Nebraska. Let the locals report them without driving up to them.

its annoying that you cant report a closure etc.. once you are out of the immediate area. you usually cant stop and do it right then. especially offramps and the like.

Hell yeah. This happened to me just this Tuesday, October 9th. All on-ramps to the 410 North (starting from the 401) were closed as far as I could tell yet Waze would not stop trying to put me back on to the 410. Had me going around and around. YES, the trick would've been to toggle on "avoid freeways" but I forgot where to toggle it thusly, didn't want to pull over on the 401 to find the setting and wasn't going to do it while driving obviously. Eventually just said f*ck it and took the first major road I could find all the way north to a proper cross road. Added about 30 minutes to my commute as a result.

I think there should be 2 new options added to waze. 1: If where you drive has 2 or more lanes and 1 or 2 lanes are closed there should be an option to show just the 1 or 2 lanes closed rather than the full road.
2: If there is temporary traffic lights due to roadworks there should be an option to show where the temp lights start and end.

Yet again, while following Waze instructions the app wanted me to take a ramp onto the autobahn BUT it had been closed. It would be so simple if I could use a voice control (or button press) “last instruction disobeyed due to road block”. Even better if this button appears for a few seconds in the corner of the screen every time I disobey the navigation instructions.

Instead I’m expected to fiddle around with the app, try and locate the junction I’d passed and then hit the correct arrow for the correct lane. This might be achievable on a huge tablet but not on a mobile phone. So for the next fifteen minutes I had to ignore waze’s attempts to take me back to the closed junction. And other Waze users weren’t warned of the closure either.

This simple button would help everyone.

Or if an accident is in the left or right shoulder.

Lane closures on the highway

I have a suggestion for the feature for reporting road closures: Don't restrict me to certain selections of locations. I recently encountered a road closure right in front of me, and tried to report it. It wasn't on the far side of an intersection. It wasn't to the right or left of the next intersection. It was right in front of me on the section of road I was already on. Let me report it where it is. Don't restrict me to an intersection. Don't restrict me to the far side of anything. Let me use my finger on the touch screen to report it where it actually is. You may restrict me to some reasonable distance of my current location. But that's all.

Just spent almost 2 hours in traffic to go <15 miles for two different lane closures. Knowing which way to merge might help.

Just spent an hour navigating around a freeway shutdown there is no way to mark and ext/on ramp as closed. WAZE kept routing me to onramp. This meant alternate routes were not avaliable to me as the application kept trying to route me back to the closed on ramp.

Add Lane Closure and Road Closure options under the Construction and Accident reporting sections.

McNicoll Ave. west of Victoria Park (Toronto, Ontario, Canada) has been narrowed down from one lane east and one lane west to just one lane (due to construction or whatever), so cars going in the opposite direction have to take turns in using the only lane that is left - first all the cars going east wait, then all the cars going west wait. This has been going on for many months. There is no way to indicate this particular situation in Waze, but people have indicated "construction" or something like "lane closures", or - can't Waze just see there is a permanent standstill there??
Yet, Waze keeps insisting I take that route. Most times, I trust it (thinking - maybe the lane reduction has ended), and end up wasting AT LEAST THIRTY MINUTES standing still on a stretch of the road that used to take 5 minutes to get through. Any other route I try taking gets me to my destination much faster (duh!)
Please fix this already! Otherwise, not sure I can keep trusting Waze to get me to my destinations faster than the alternatives.
Thank you.

This feature suggestion is required

Good Idea

I agree that would be a great idea!

Additionaly, even if it is mapped as two 'one way' segments, it might be good to allow them both to be closed, or even if just the other direction has an accident, there should be a way to close it.

I think it would be a great option that when you go to close a road, if the road you are closing is a 2 way segment then there should be a pop up asking if the closure is one way or both directions. I reported a closure today and the app only made it one way when it was actually both ways.
