Intensive through Work by All-lane Closures

This method aims to minimize the impact on traffic in a central city area by conducting road construction intensively at one time. Major construction targets include road paving and expansion joints.
Hanshin Expressway adopted this method in 1973, and has carried out maintenance work using it under it approximately once every year since 1985.
Before starting such intensive maintenance work, we always request cooperation from the public through a publicity campaign and intensive advertisement.
