[Construction Case] Yokohama Ring North Line Namamugi Junction New Construction Project

Contributing to traffic congestion relief and environmental improvement! We are implementing construction using very specialized and high-difficulty methods.

The "Yokohama Circular North Line" is a dedicated highway that connects the "Kohoku Interchange" of the Third Keihin Expressway to the "Namamugi Junction" of the Yokohama Bay Bridge, forming the northern section of the Yokohama Circular Road, which is the backbone of the Yokohama City transportation network. In our construction section, in addition to the main bridge section directly above the Yokohama Bay Bridge, we are also constructing and erecting ramp bridges that connect from the "Kinkou Junction" area to the Bay Shore Line and the Third Keihin Expressway. To minimize road closure times, we transport large bridge girders assembled within a limited area to the designated location using a multi-axle trailer with 96 wheels, and then they are erected all at once by a super-large crane that self-propels to the same designated location. 【Project Overview】 ■ Route Name: Yokohama Circular North Line ■ Construction Period: September 1, 2011 - October 29, 2015 (at the time of contract) ■ Construction Location: 1st and 2nd Chome, Namamugi, Tsurumi Ward, Yokohama City *For more details, please refer to the PDF document or feel free to contact us.
