    I may have a project in the near future that will require 1,500 of the worlds largest tunnel boring machines.
    and 50,000 heavy trucks.

    Building a 4 lane freeway all the way around the entire North America Canada and Alaska alone the shore line of the sea.

    Building bridges over small sections of water of 30 miles from land to land or Island to Island where there is a mountain or hill these largest tunnel Boring machines will be use in places needed to drill and dig a tunnel for a freeway to get through if the tunnel has to be over 50 miles long in places or more.

    freeways in farthest north of Canada no one never gone before.

    More future projects of cities under ground or in 1 big one big indoor building cities in places where weather is to cold.

    35,000 miles sea coastal 4 lane freeway and another 150 miles of 4 lane freeway tunnel under Chukchi Sea from Wales Alaska to Russia.
