Generate Polygon Plane from Array

Hello there. So I am trying to generate polygon plane (as a road) using by array I have which contains Vector3 items.

First, I draw a bezier curve, according to points on bezier curve, I determine bounds of my path. Now I'm trying to reshape/create a plane with those points to shape it into desired path.

     void DrawMesh()
     {
         Vector3[] MeshBounds = new Vector3[CurvePoints.Length * 2];
         Mesh mesh = Pathmesh.GetComponent<MeshFilter>().mesh;
         mesh.Clear();
         int index = 0;
         foreach (Vector3 point in CurvePoints)
         {
             MeshBounds[index] = new Vector3(point.x - 5, point.y, point.z);
             MeshBounds[index] = new Vector3(point.x + 5, point.y, point.z);
         }
 
         mesh.vertices = MeshBounds;
         List<int> Larray = new List<int>();
 
         for (int i = 1; i < CurvePoints.Length-2; i++)
         {
             Larray.Add(i - 1);
             Larray.Add(i);
             Larray.Add(i + 1);
         }
         mesh.triangles = Larray.ToArray();
 
         mesh.RecalculateBounds();
         mesh.RecalculateNormals();
         mesh.name = "Path";
         Pathmesh.GetComponent<MeshFilter>().mesh = mesh;
     }

This is the piece of code that I'm trying to draw/reshape plane polygon. Problem is I can't see anything in the scene(Yes added to the scene).

What might be problem, which part of my approach is wrong ?

Edit1:

Just an idea, maybe creating saparate planes for each point and merge them with combine would fix my problem(ignore the code above). Result; alt text
