What this guide does
This guide explains how to use the Data Import Tool to add specific segments to an existing network.
This guide is useful when new assessments or projects identify additional roads that should be included.
This guide covers bulk additions where you already know which segments need to be added.
Prerequisites
NHVR Portal (NHVR Go) account with Road Manager access.
Access to the network you want to update.
Permission to create or edit a Network Update Request (NUR).
A list or dataset identifying the new segments to be added.

Step-by-step instructions
Open NHVR Go in your browser and log in with your Road Manager account.
From the menu, select Access management, then select Vehicle networks so the Vehicle Networks table is displayed.
Locate the relevant network and create a Network Update Request (NUR) or open an existing NUR. Click Save Draft. Be sure not to submit the NUR as the select Import network segments option will not appear.
4. Click the three dots (⋯) next to the NUR number and select Import Segments.
Choose to upload using a template and download the template.
6. Open the template in Excel and locate the scenario Add Segments to A Network.
7. Complete the template with:
a) The details of the specific segments you want to add.
b) The access level that should apply (for example approved, conditional or restricted), as indicated by the template.
c) Any associated conditions or restrictions, if required.
8. Note that if a road segment is already on the network, it must be removed first before it can be added back with a new access level.
9. Save the completed template as a CSV.
10. Upload the template into the Data Import Tool by dragging and dropping the file.
11. Wait for the system to validate the data and correct any invalid fields before re-uploading if necessary.
12. When validation passes, click Import Data. The specified segments will be added to the NUR and, once approved, to the network.
13. After receiving the completion notification, return to the NUR and confirm the new segments appear as expected.
Tips and common issues
This scenario is helpful when a new assessment (such as a state-wide bridge assessment) results in many roads becoming available for access at once.
If a segment is already on the network, remove it first in a separate step before re-adding it with a new access level via this scenario.
Keep your segment list accurate and up-to-date to avoid adding incorrect or duplicate segments.
Where to get help
Consult your internal engineering or asset teams to confirm which segments should be added to the network.
Contact the NHVR Network Management or Spatial support team if imports fail due to segment identification issues.
