I’ve added some new roads to the map in Burnley, but there’s an auto L4 lock on the main road they attach to, so I’ve ended up with detached nodes.Could someone join the nodes up please? Disconnected roads selected in link, main road below them.
I’ve done that.
Welcome to the (additive) worlds of Waze editing. You might want to look at the following web pages if you intend to continue mapping:
UK Editing Policies and guidelines
The UK Wazeopeadia Page
I would just like to point out a few things about your edits:
You should also make sure the new roads you’ve input have ‘none’ set in the street address, and either Burnley or ‘None’ set in city. I also suggest car parks like this should be set to Parking Road not Private Road.
Please don’t enable u-turns as they can cause strange routing.
These segments are in a closed loop. You need to ensure no two segments are connected to each other at both ends. Just cutting one segment will resolve that issue.
You shouldn’t map every parking lane in a car park. Just a main routes through the car park is good enough. GPS isn’t that accurate to pin point which parking aisle you’re in.
Thanks for doing that and for the pointers, it’s been a good 7 years since I edited the Waze map 
Will make the appropriate updates. [edit] Looks like I was beaten to it Cheers for that. I know for the future.
