Crittec Co., Ltd. has officially launched the co-creation project "100-Year Bridge Project," which aims to promote the appeal of the bridge, civil engineering, construction, and infrastructure industries, starting from July 27, 2026. A press release regarding this project has also been distributed. The "100-Year Bridge Project" is an initiative aimed at connecting people, companies, and ideas through the symbol of a bridge, and conveying the value and importance of social infrastructure to the future. In response to our call for ambassadors, various companies and individuals from different industries and positions, including the bridge, civil engineering, and construction sectors, as well as power infrastructure and tourism guides, have participated. Moving forward, we will leverage each perspective to collaboratively share the appeal and importance of social infrastructure. We will continue to work with our ambassadors to widely disseminate information about bridges and social infrastructure through social media and various media outlets. Additionally, this project is continuously seeking ambassadors from companies, organizations, schools, and individuals. Please pay attention to the activities of the "100-Year Bridge Project."

Durability 100 years, expansion device, hybrid joint, type 3LII.
A bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].

**Features** 1) Ultra-long durability of 100 years: Achieved 12 million cycles in fatigue loading tests by a third-party organization, proving a durability of 100 years. 2) Long-term water-tightness of 50 years: Proven water-tightness equivalent to 50 years through water-tightness performance tests by a third-party organization. Secondary water-stop materials are standard specifications. 3) Large expansion and contraction capacity and wide gap compatibility: One of the largest expansion capacities among NEXCO-approved products. Capable of accommodating expansion from 150mm to 350mm and maximum gap of 730mm. 4) Ultra-low noise and vibration-free: A vertical integrated structure with 32mm thick steel plates arranged vertically and alternately, making it difficult for air vibrations to transmit under the beams, thus reducing noise. Smooth and comfortable driving experience. Small wheel load support intervals make it less likely for impact vibrations to occur during driving. 5) Easy to install: Can be constructed without road closures, using lane restrictions that allow shared use of one side for both new installations and repairs. Lighter compared to conventional large products. 6) Maintenance-free: The load support plate and anchor plate have a vertical integrated structure with high durability. Additionally, the structure prevents damage from metal fatigue, allowing for visual maintenance management. Visual inspections are sufficient, eliminating the need for regulated sound inspections. 7) NETIS registered: This is a new technology registered in the Ministry of Land, Infrastructure, Transport and Tourism's database system "NETIS." Registration No. KT-210067-A.
