Emergency vehicles can pass by regular passenger cars! It is compatible with Type B and Type C vehicle protection barriers!

"Road Plus" is a cantilever road widening method that allows for a maximum road width increase of 1.75 meters in a short period by installing it on the shoulders of existing roads. Due to its cantilever structure, excavation of the hillside is unnecessary, and the impact on valleys such as rivers and waterways can be minimized. By using precast products, temporary construction can be reduced, leading to shortened construction periods, and it can accommodate both large vehicle specifications and medium vehicle specifications according to regional characteristics.
