[Published in the January 1, 2026 issue of Bridge News] "Hybrid Joint Type 3LII" adopted for Meishin Concentrated Construction! Introduced as an advanced example of large finger joint replacement.
Recently, an article about Crittec Industries' construction achievements was published in the January 1, 2026 issue of the Bridge News. The article highlights a case where, during the concentrated construction of the Meishin Expressway conducted in November 2025, a large finger joint was replaced with our "Hybrid Joint Type 3LII." The background for receiving this construction order was a similar replacement project carried out in 2024 within the jurisdiction of the Kyoto Expressway Office of NEXCO West Japan's Kansai Branch. This construction is noted as the first case in the Kansai Branch area where a large finger joint was replaced with a product joint, and the high evaluation of this achievement led to its adoption in the concentrated construction of the Meishin Expressway. Replacing large finger joints with product joints is a field with few precedents and high technical difficulty, leading many companies to hesitate in responding. In this context, our Hybrid Joint Type 3LII, which possesses reliable technical capabilities and construction achievements, was selected. For any inquiries regarding expansion devices, please consult Crittec Industries.
