Four. Construction overview
Tohoku Expressway In-bound Line Sano SA lamps will be replaced with expansion and contraction devices due to seismic reinforcement work. In addition, we will also repair and inspect the road lighting inside the lamp, and repair the ETC equipment of smart ICs. Since the place where these works are carried out is one lane and it is not possible to carry out the work under normal lane regulations, it is necessary to close the lamp and carry out the work.
Therefore, in order not to cause any inconvenience to customers, we will close the lamps on weekday nights when there is little traffic, and carry out the construction intensively and efficiently.
This work is necessary to use Expressway safely and comfortably, so we ask for your understanding and cooperation.
