# How to add a Junction node

Please note, this guide refers to the urban Junction node, however the same method applies for urban Outfall, Flow-Divider and Storage nodes.

On the **1D Urban Build tab**, initially confirm you are in **1D Urban selection mode** by ensuring the toggle is coloured blue.

Click the **Junction** icon and it will be highlighted. Then on the **map** view, click the location you would like to add the junction.

The node will automatically be added to the **Nodes** tab of the **1D Urban Network panel**. It will be pre-filled with values and options set on the **Model Defaults** window, recall how to edit these defaults from the [Urban Networks](/v1/docs/1d-urban-networks) section.

As the **Multiple** checkbox is ticked by default, continue to click the map in more locations to add multiple Junction nodes. Click the **Junction** icon again to de-select when you have finished adding the junctions.
