Hi alain2003,
Thanks for sharing the references and for your work on the map!
According to highway=primary, the primary classification already serves well as a major road connecting cities and areas, even before the expressway is fully completed.

It’s also important to keep the road network hierarchy consistent, ensuring higher-class roads connect smoothly to lower ones.
Thanks again for your contribution!
Best regards,
