Also, are you positive way/1457853950 exists? The southern entry of the culvert has no visible trace in aerial footage

Thank you for your edit!

I noticed you added way/1457853951 which is disconnected from downstream. I am almost sure this flows beneath the highway and immediately connects to Nahal Bustan via way/232061377

I've reconnected it in changeset/176182381

Hello! Thank you for the updates.

It seems that you accidentally disconnected way/548728490 when you removed the nonexisting bicycle track.

See here:
