How can I fix the issue of my road object being smaller than expected in Unity?

Creating and stretching an object is not working properly.

I am trying to create a road system for a 2D top-down project in Unity. The process is simple:

1. User clicks on the screen, preview line appears
2. Preview lines follows the mouse cursor
3. After the second click endpoint is set and line transforms into a gameobject with the same size and position as a line.

Everything works until transformation, basically code creates the object, but it's much smaller than expected. Here are some screenshots:

Preview line works as expected
Object created after second click (preview line on previous screenshot)

using UnityEngine;

public class RoadBuilder : MonoBehaviour
{
    public GameObject roadPrefab; // Prefab to instantiate the road
    public LineRenderer previewLine; // LineRenderer to show the temporary road preview

    private Vector2 startingPoint; // Starting point of the road
    private Vector2 endingPoint; // Ending point point of the road
    private bool isBuildingRoad; // Flag to indicate if the user is currently building a road

    private void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            if (!isBuildingRoad)
            {
                // Start building road
                isBuildingRoad = true;
                startingPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                previewLine.positionCount = 2;
                previewLine.SetPosition(0, startingPoint);
                previewLine.SetPosition(1, startingPoint);
            }
            else
            {
                // Finish building road
                endingPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                CreateRoad(startingPoint, endingPoint);
                isBuildingRoad = false;
                previewLine.positionCount = 0;
            }
        }
        else if (isBuildingRoad)
        {
            // Update road preview
            Vector2 currentPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            previewLine.SetPosition(1, currentPoint);
        }
    }

private void CreateRoad(Vector2 start, Vector2 end)
{
    // Calculate road position
    Vector2 roadPosition = start;

    // Calculate road size and rotation
    float roadSize = Vector2.Distance(start, end);
    float roadRotation = Mathf.Atan2(end.y - start.y, end.x - start.x) * Mathf.Rad2Deg;

    // Instantiate the road game object
    GameObject road = Instantiate(roadPrefab, roadPosition, Quaternion.Euler(0f, 0f, roadRotation));
    road.transform.localScale = new Vector3(roadSize, 1f, 1f);
}



}

To achieve the same effect, you need to do two more things in the sprite import settings

1. Change Pixels Per Unit to 32, so that the edge length of the sprite becomes 1 in the world.

2. Open the Sprite Editor, change Custom Pivot to X:0 Y:0.5 (the middle-left of the sprite)
