Floor marking: large scene question

Hi,

I’m creating a large scene with floor marking on a road, it looks like the one I’m sharing. I must be able to land on the ground it must be “pixel perfect”. The freeway has entries and exits so I don’t think you use the technique Zak Parrish used in the Spline tutorial (Using Splines & Spline Components | Live Training | Unreal Engine - YouTube : the spline aligns and deforms multiple components) because I cannot change how the real road is. I don’t know how to do as a huge texture would cost a lot of resources… no?

How would you make floor marking in a large scene when you have to match reality? Your experience would be very useful. Thank you.
