Main local road Harajuku Rokutsuura (Kasama Intersection)

 The main local road Harajuku Rokutsuura Kasama Intersection is a key point of transportation where the prefectural road Harajuku Rokutsuura (circular Route 4) and the prefectural road Ofuna Stop Yabe, Kasama Route 139, and Kasama No. 142 intersect. At present, chronic traffic congestion is occurring due to the complex shape of the intersection.
 This project aims to alleviate traffic congestion and improve safety by improving the intersection shape and constructing a four-lane prefectural road Harajuku Rokutsuura to reduce traffic congestion and improve safety. We are also promoting disaster prevention and reduce disaster damage measures, such as the electric wire joint ditch project.
