Horizontal Nether coordinates map to the Overworld at an eight-to-one scale, so one block of Nether travel can represent eight Overworld blocks. Players turn that leverage into long tunnels and marked routes. A highway is player-built infrastructure, not a promise that the route is safe, intact, or trap-free.
Scope: Horizontal Nether travel and player-built routes; exact portal linking and highway condition remain version- and server-specific.

The Nether portal reference documents the horizontal coordinate conversion that makes Nether travel distance-efficient.
