<p>The invention relates to the method and installation for building highways. The aim of the invention is to extend operational capabilities of a mobile installation for building a highway in space-limited environment without reducing the traffic intensity, and to build the highway above an existing main traffic artery. The inventive method consists in building the highway in the form of an elevated road passing at least by the part thereof over an existing motor road and is characterised in that a portal-type mobile installation, preferably self-propelled is used. The movable legs of said installation are disposed within the land allocation of the existing motor road.</p> |
