is/was

Xiaohan Road is/was located mainly in the city of Sanmenxia. The majority of the ancient road has now lost in the mist of history, only the Shihao section survived. Archaeological investigation shows the Shihao section is approximately 230m and in a generally NW-SE direction. (self-made)

As pointed out in the above paragraph, most of the ancient road no longer exists or cannot be seen on the ground. So, what tense should be used? Although I know it is correct to say "Beijing is an ancient city.(though it is quite a modern city nowdays)" this question really confuses me. Please help me out. Thank you!

Does the city of Sanmenxia still exist?

Yes, it does.

The majority of the ancient road has is now lost (or has now been lost) in the mist of history, only the Shihao section survived.

If this is true then it is safe to say that Xiaohan Road can no longer be considered an entity. I would use was.

If the Xiaohan Road refers to the remaining section, can 'is' be used?
Nowadays many tourists visit the Xiaohan Road which is located in the Sanmenxia City.

Is the underlined part in "The majority of the ancient road has is now …" commonly used or should we use a slash, please?

[Matthew Wai]

Or should we say 'The majority of the ancient road has been lost ...'?

I have to point out the comma splice. You need a period or semi-colon where you have a comma in the second sentence.
