The HWU-linked May 2025 highway map records this route as 6 blocks wide and 4 blocks high. These are the map's dated construction dimensions. MEG's April 2023 project report also records these dimensions for the full route. MEG reported completing the 6-wide, 4-high tunnel to the Nether world border on April 30, 2022. Credited diggers: Hare_Hare_Yukai and harritaco. The completion dates were published in MEG's January 1, 2023 announcement; they describe the tunnel excavation, not the later paving work.
Clearance: 4 blocks
