3. Construction overview

Since the sound insulation wall is damaged at the exit ramp of the Gulf Chiba IC on the Higashi-Kanto Expressway In-bound Line, we will carry out sound insulation wall repair work. The section where this work is to be carried out is one lane, and since it is not possible to carry out construction under normal lane regulations, it is necessary to close the ramp and carry out the work.
Therefore, in order to minimize inconvenience to our customers, we will close the ramps on weekday evenings when traffic is low, and carry out construction intensively and efficiently. This is necessary for the safe and comfortable use of the Expressway, so we ask for your understanding and cooperation.
