NEXCO EAST Kisarazu Construction Office (Kisarazu City, Chiba Prefecture), E14 Tateyama Expressway (hereinafter "Tateyama Road") Kimitsu Interchange (hereinafter "IC")-Futtsu Takeoka IC We are implementing a 4-lane construction, but this time, the bridge girder construction of Aikawa Bridge has been completed. As a result, all bridge construction for the 4-lane construction section has been completed. We will continue to proceed with the construction, so we appreciate your understanding and cooperation.

We would like to inform you about the current status of the four-lane project from Kisarazu Minami Junction (“JCT”) on the Tateyama Road to Futtsu Takeoka IC.

Between Kimitsu IC and Futtsu Chuo IC, the lanes of the temporary 2 lane section (1 lane on each side) have been changed and construction is being carried out on the side of the median strip, at 2019 We are planning to start 4-lane operation. In addition, between Futtsu Chuo IC and Futtsu Takeoka IC, it was confirmed that the condition and geology of the bedrock differed from the assumption, it took time to construct structures such as bridges and retaining walls, and the start of pavement work was delayed. It was difficult to convert to four lanes this year. Going forward, we will do our utmost to make 4 lanes as soon as possible, aiming for completion within 2019.
