A method and apparatus for forming a tunnel structure at a relatively shallow depth from the surface, which tunnel can be used as a replacement or additional transport route to an existing transport route (2) which is already formed on the surface. The method comprises the steps of forming two spaced apart access tunnels (hatched portion) to expose the tracks, introducing units (22) comprising side walls portions (26, 28) and a roof section (30) by moving the units along the tracks while excavating the soil in which the tunnel is to be formed is in advance of the leading edge of the units.

Systems, methods and apparatus are provided through which in some implementations a method of a tunnel construction includes inserting two guidetubes into a ground; connecting a sheet to ends of the two guidetubes; and hammering the sheet through the ground from the ends of the sheet that are opposite of the two guidetubes, thus pushing the two guidetubes through the ground in the same direction as the sheet and another method of tunnel construction that includes inserting two guidetubes into a ground; and hammering a sheet into the ground with a beveled front edge of the sheet directed toward the two guidetubes, where the beveled front edge directs the sheet toward the two guidetubes.
