highway project

Highway project:
Miner Crew: From 0x 0y of spawn and build 4x2 tall tunnel always staying on either x0 with you mining in a + or - direction or you mining in the Y direction with your X staying on 0

Cover Crew: Make the sides ready for the ice crew, make it so there is no gaps when the slabs are in place so no ghast can target you.

Ice Crew: we will fill in the 3'rd layer with packed ice for easy boat travel. The reason for the 3 block head space is encase any user wants to rid their horses.

Extra info: If your base is near the highway or is off the axes your building on then mark it with a sign and a miner will build out your way, please mark the portal cords for easy location

For miner crew: if you see a nether fortress mark it with a sign and keep moving.
For cover crew: Your free to use any block you want but recommending cobble due to it being immune to explosions.
For ice crew: make the ice in a checkerboard pattern and in the other spaces have slabs to prevent as much spawning.
