Precursor Sky bridges

I’ve heard and read some information about them but how expansive where they?
I know they connected worlds but how, like the orbital elevators?or was it by some other means?
I know that the flood used em against the forerunner but did the forerunner use them themselves or no?

Star roads, or unbending filaments, were several kilometers thick and spanned entire solar systems, connecting/linking planets and even stars. Some of the planets, they had orbital and suborbital structures like Human orbital elevator. Precursors use something called neural physics, which they use in everything. The Flood was able to use the star roads after the Primordial (a Precursor) took control of the Gravemind. No, no one has ever been able to tap into/use them as no one has any comprehension of Precursor tech. The Precursors are hundreds of millions of years beyond the Forerunners. Hope this helped out.
