[Metal Road Construction Method Case Study] Nara Prefecture Road Improvement Project

Ensuring safe and smooth passage! Case study of road improvement work on National Route 425, Jūzato to Sakon Nishikawa section (II-2 section).

National Route 425 in Nara Prefecture is a road that facilitates regional exchange, connecting the city of Gobō in Wakayama Prefecture and the village of Totsukawa in Yoshino District, Nara Prefecture. However, there are continuous sections with narrow widths and poor alignment, making it difficult for vehicles to pass each other in many areas. Therefore, construction was carried out with the aim of eliminating narrow width sections, ensuring safe and smooth passage, and contributing to tourism promotion. The site is located within the area of the World Heritage Kumano Kodo, and due to the need for consideration of the landscape and the preservation of water channels, the metal road construction method was adopted. 【Case Overview】 ■ Client: Nara Prefecture, Gojō Civil Engineering Office ■ Construction Period: January 5, 2022 – June 30, 2022 ■ Total Length: 19.0m ■ Width: 6.95m *For more details, please refer to the PDF document or feel free to contact us.
