I saw the other thread regarding this location and concur with CBenson that the different levels shouldn’t cause a routing issue but I did go ahead and set the segments to level 0. I didn’t unlock them but if this is problematic (the previous locks were at L4), let me know either here or via PM and I’ll unlock them.
I’m guessing that, since that little median segment is so new (created on March 24) Waze is routing people over it in order to collect data.
IMHO, I’m not 100% certain on this but couple of weeks ago, I helped an editor who was having similar issue. Waze would route least favorable road. Although, there was no bridge or ramps but few of the segments were 1’s and 0’s. They were not consistent. After, he changed them all to 0, since there is no bridge, etc. routing worked perfect.
