3. Construction overview

Along with the construction of the Tokyo Outer Ring Road (Kanetsu-Tomei), we will carry out the construction of a bridge that crosses over Mejiro-dori. In this construction, the bridge girders assembled in advance within the work area of the construction site will be transported to the bridge piers by passing over Mejiro-dori using a delivery device (trolley).
Since this construction will pass over Mejiro Dori and near the Oizumi Interchange with heavy traffic, these roads will be closed during construction in consideration of safety. Therefore, in order to minimize inconvenience to customers, we will carry out construction work intensively and efficiently at night on weekdays when there is little traffic. We ask for your understanding and cooperation.
In addition, we plan to close the road in the same manner in the future. Details will be announced later.
