Why does this happen on the road

Show a screenshot of the wireframe in that section, wondering what the mesh looks like

 

OK

 

i bet on "road part too long" or "normals not pointing up" at this place

 

Thank you, that help is always a pleasure, thank goodness it was only a low-traffic road, I did it in 3 and it worked, they already told me that in RTB the roads are pulled in 1km if they do 15km from them in 1km. Thank you very much solved
