PURPOSE: A lightweight soundproof tunnel is provided to remarkably reduce the extension of the soundproof tunnel by effectively reducing noise discharged from the soundproof tunnel. CONSTITUTION: A lightweight soundproof tunnel comprises concrete foundations(10), multiple skeleton frames(20), braces(30), roof soundproof panels(40), and side soundproof panels(50). The concrete foundations are installed along both sides of a road. The skeleton frames are composed of steel pipe columns(21) and truss type roof members(22). The steel pipe columns are vertically positioned at the concrete foundations. The truss type roof members are connected to the top ends of the steel pipe columns. The braces connect the adjacent skeleton frames to each other. The roof soundproof panels are installed between the truss type roof members. The side soundproof panels are installed between the steel pipe columns.
